Introduction
This users’ manual is to provide necessary information to the users of 1600m3 Acoustic Test

Facility (referred to as “this facility” hereafter) located in Spacecraft Integration and Test Building.
The information contained in this manual is limited to this facility. For further information on theSpacecraft Integration and Test Building in which this facility is located, refer to “vol. 1 Common
Matters (GCA-02006)” of “Users’ Manual for Spacecraft Integration and Test Building.”
This facility is used for acoustic tests on spacecraft, etc., and is capable of performing not only
qualification/acceptance tests on satellite systems and subsystems, but development tests, or the like,to see the acoustic durability and vibroacoustic properties of materials, and so on.
This facility has the performance and specifications that can satisfy acoustic tests on large andvarious kinds of test specimens (■abbreviated as TS hereafter), e. g., satellites, that are launched byan H-IIA launch vehicle, etc.

Brief Overview of this Facility Brief Overview of this Facility

2.1 System Outline
The system diagram of this facility is shown in Figure 2-1. This facility broadly consists of asound generating system, a monitor and control system, a reverberation chamber system, a dataacquisition system, and other utility equipment.

2.1.1 Sound Generating System
The sound generating system is made up of a GN2 system, a sound generator, and a soundspectrum control system. The GN2 flow generated by the GN2 system is converted into sound by thesound generator. Meanwhile, the sound spectrum control system controls the sound generator theway pre-input test specifications can be satisfied. The sound generating system is so to speak a set ofsignificant devices to produce the acoustic energy necessary for forming a sound field and control
the sound source to form any type of sound field.
The users of this facility are to draw up the test specifications (target sound pressure level, load
time, etc.) to be pre-set into the sound spectrum control system (control computer) before starting a
test, following the form in section 4.2.

2.1.2 Monitor and Control System
The monitor and control system is composed of a facility controller and a safety monitor device.
The facility controller is made up of a control console, equipment racks, display panels, etc., andcontrols the sequence of equipment including all sorts of interlocks.
The safety monitor device consists of a monitor device that visually monitors and records the1This may not be the latest edition.

behaviors of the oximeters attached to several parts of this facility and a TS during a test, and abroadcast communication system that enables communications between workers.

2.1.3 Reverberation Chamber System
The reverberation chamber system consists of a reverberation chamber and equipment belonging
to it.
This facility adopts a diffused sound field produced in its reverberation chamber, and thechamber is therefore a key factor to determine the performance of this facility. The reverberationchamber in this facility is designed and manufactured the way it can store a TS and produce a
diffused sound field in it.
The reverberation chamber is the only I/F to a TS in this facility, where test configuration andpreparation are to be based upon the effective area in the chamber, the movable range of a crane, thehole pattern on the floor, etc. The details of the users’ I/F in the chamber are shown in section 3.2.1.
Upon the roof of the chamber, there exists a reverberation chamber ventilation system toventilate the chamber after performing an acoustic test.

2.1.4 Data Acquisition System
The data acquisition system, being made up of a measurement and control device, an operation
PC, and an analysis PC, measures and records the acceleration data (200 chs) and strain data (32 chs)
at different parts of a TS, as well as the sound pressure data in the chamber (36 chs), and performs
various analyses on the data. It can also acquire acceleration data with up to 602 channels byadopting the measurement rack of the large-scale separation shock test facility. Contact AES when
acceleration measurement with 200 channels or more is planned.
The details of the devices that make up the data acquisition system are shown below.
The measurement and control device allows the real-time amplification and A/D conversion of
the analogue signals of acceleration/strain/sound-pressure data, and records them in the hard disk.
The operation PC is equipped with a function to operate the measurement and control device via
various settings (sampling frequency, sensor sensitivity, measurement range, etc.)
The analysis PC executes various kinds of analyses (octave analysis, PSD analysis, etc.) on
measurement data.

2.1.5 Utility Equipment
The TS dolly, which is one of the main devices among the utility equipment, functions both as araising jig and a moving dolly, which helps efficient test preparations with a TS. Refer to the I/Fshown in section 3.3.3 when using the TS dolly.

2.2 Main Specifications
2.2.1 Total Performance
The main specifications of this facility are shown in Table 2-1. The maximum sound pressurelevel in the empty sound field is 151dB (overall), and the capacity of the reverberation chamber isabout 1600m3. The empty sound field denotes the sound field in an empty reverberation chamber,and the actual maximum sound pressure level is therefore more or less lower than 151dB due to thesound absorption by a TS or other reasons.
A sound field (sound pressure spectrum) is controlled by the sound spectrum control system inreal time. The controlled variable is calculated by the computer (a component of the sound spectrum
control system) based on the actual sound pressure level acquired by the control microphones (up to6) placed in the reverberation chamber and the pre-set target sound pressure level. Then, the electric
signals and GN2 gas are controlled before being sent into the electro-pneumatic transducer and thejet nozzle (both are the components of the sound generator).
The 1/1 octave band sound pressure spectrum and control accuracy for the maximum overallsound pressure level of 151dB are shown in Table 2-2. (The control accuracy denotes the difference
between the actual sound pressure level and the target sound pressure level (dB) indicated for each
1-1 octave band.)The settable range of target levels is shown in Figure 2-2. One can set a sound pressure spectrum
in a continuous curve, not in discrete steps, that corresponds to the frequencies in this range as a test
condition. (The target levels can be set as a 1/3-octave-band sound pressure spectrum.)
Also, there are cases where the sound pressure cannot be controlled to be within the target soundpressure levels when performing a test in unique conditions (e. g., when the spectrum is discrete orwhen only specific frequency bands have high levels, etc.) Especially, it is known that the highsound pressure level at 200Hz (1/3 oct. band) influences on high frequency bands at its high orderharmonic frequencies such as 400Hz or 800Hz turning out to exceed the target levels. To avoid suchphenomena, the pre-set accuracy is to be checked by loading preliminary sound before a test, so thatthe target/allowable levels can be changed according to the results if necessary.
The precise performance and specifications of the component devices/equipment in this facility
are described in the “Device I/F” in section 3.2.

2.2.2 Data Acquisition System
The data acquisition system allows the measurement and recording of the acceleration/strain dataof different parts of a TS and the sound pressure data in the reverberation chamber, and performs
various types of analyses on the data. The functions and performance of the data acquisition system
are shown in Table 2-3.
Furthermore, the acquisition of acceleration data with 602 channels in total can be achieved byusing a data acquisition system on the measurement rack of the large-scale separation shock test
facility in addition to the original data acquisition system. That, however, accompanies the following
restrictions due to the difference between the two data acquisition systems.
・ Transfer function analysis cannot be performed between the data acquired by the two dataacquisition systems mentioned above.
・ The data acquisition system on the measurement rack of the large-scale separation shock test
facility is not equipped with an automatic range adjustment function (section 3.2.2.)
The functions and performance of the data acquisition system on the measurement rack of thelarge-scale separation shock test facility are shown in Table 2-4.

Users’ I/F

3.1 Layout
This facility is located at the southeastern end of the Satellite Integration and Test Building(SITE) in Tsukuba Space Center, with its reverberation chamber, GN2 system, and sound spectrum
control system respectively located in the acoustic test room, the acoustic machine room (the firstfloor), and the acoustic measurement and control room (the second floor.) The basic working areasfor users are limited to the acoustic test room, the acoustic measurement and control room, the foreroom of the unpacking room, and the assembly preparation room (in some cases the check-out room
is included) assigned to users. For further information on the assembly preparation rooms, refer to“vol. 1 Common Matters (GCA-02006)” of “Users’ Manual for Spacecraft Integration and Test
Building.”
The layouts of the acoustic test room and the acoustic measurement and control room, which are
the main working areas for users, are shown in Figure 3-1.
The satellite path and all the assembly preparation rooms are cleanrooms with ISO class 8 level(class 100,000.) The reverberation chamber is not equipped with a ventilation system, but isstructured the way clean air flows into the chamber from the satellite path when the heavy door (thedoor standing between the satellite path and the reverberation chamber) is open.
The acoustic test room consists of the reverberation chamber, the chamber fore-room, and thechamber outer-rooms. The chamber fore-room is sandwiched by two heavy loading dock doors andmitigates the leaks of noise. The chamber outer-rooms, where the main equipment of the soundgenerator is placed, are also made to mitigate noise.
User workers have two routes to enter the reverberation chamber; one is “the acoustic
measurement and control room on the second floor ~ the air shower room on the first floor ~ theouter-room ~ the reverberation chamber” and the other is “each assembly preparation room ~ thesatellite path ~ the reverberation chamber.” Meanwhile, workers are to keep out of the area shown in
Figure 3-2, the acoustic machine room, and the tank yard (that is, the areas between the acoustic
measurement and control room on the second floor ~ the air shower room on the first floor, and thesatellite path ~ the outer-room and the reverberation chamber, are locked with electrical locks to
keep out workers) for the sake of safety because GN2 flows into the reverberation chamber during an
acoustic test.
The configuration of the sockets in and around the reverberation chamber is shown in Figure 3-3.
The sockets with a single-phase circuit are 100/115V each, and those with a triple-phase circuit are
200V each. The one with 200V (50A) is used as the drive power supply for the TS dolly shown insection 3.2 (3.)
Use the distribution boards equipped in this facility for the power supplies of large-capacity
devices, e. g., a TS check-out device. Refer to Appendix A for the details of distribution boards

3.2 Device I/F
The I/Fs of the reverberation chamber system, the data acquisition system, and the facility
equipment system, which are related to users, are shown below. In case the details of the systems or
the specifications and performance of any device that is not encompassed in this manual arenecessary, contact AES.

3.2.1 Reverberation Chamber System I/F
The reverberation chamber is a cuboid with the dimensions of 10.5m (width) × 9.0m (depth)
× 17.1m (height.) The dimensional diagram of the reverberation chamber is shown in Figure 3-4.
A TS is carried in/out to/of the chamber through the heavy door on the wall facing the satellite
path. The aperture of the heavy door is approximately 7m (width) × 13m (height.)
On the wall there are a measurement relay unit that transmits the measurement signals of a TS to
the data acquisition room, a patch panel, lighting equipment (a mercury lamp, a preliminary
fluorescent lamp), and ITV cameras installed. Meanwhile, the three walls other than the one with theheavy door have side-wall rails at the heights of 6m and 12m. The rails which withstand the tensile
load of 500 kg are effective for fixing jigs, or preventing them from turning over, for example. The
diagrams of the wall faces are shown in Figure 3-5.
On the ceiling, a crane for handling a TS is being set. It is an X-Y travel motion type, with acapacity of 10t and height of 15m beneath its hook. The movable range of the hook is shown in
Figure 3-6.
The floor of the reverberation chamber is made of stainless steel plates in its center area of 5m
× 5m, and steel plates with epoxy coasting in the rest of the area. There are 89 screw holes (for M20 bolts) on the floor, which can be used for fixing TS jigs, microphone stands, etc. The screw holes
pattern is shown in Figure 3-7 (1/2)(2/2).
The rough dimensions of a TS that can be set in the reverberation chamber are presented in
Figure 3-8. The several cases shown here are based on the idea that the volume of a TS is 10% orless of the reverberation chamber volume. In addition to that, the aperture size of the heavy door andthe state of sound field are to be taken into account in an actual test.
There are some points to be careful of to load a well-conditioned sound field on a TS.
First of all, a TS needs to be placed in a location where the influence of reflected waves(standing waves) from the surfaces of the reverberation chamber is little. Also, it is desirable to keep
enough distance (basically, 1/4 or longer wavelength of the lowest frequency of the test condition)
among microphones, between the microphones and a TS, and between the microphones and thechamber walls, to help control microphones (at least 4 of them) to obtain accurate sound field data.
As for other general test methods, refer to “JERG-2-130, Satellite General Test Standard.”
Taking the above into account, users are to plan for the test configuration in the reverberation

3.2.2 Data Acquisition System I/F
There are a measurement relay unit (cf. Figure 3-10) and a patch panel (cf. Figure 3-11)
equipped in the reverberation chamber as the I/F between a data acquisition system and a TS to relay
the cables from sensors. The cables that fit the connectors on the front face are to be prepared andconnected by users. Meanwhile, a bridge box for strain measurement and the microphones andcables for sound pressure measurement are prepared by the facility-side personnel. How to connect a
bridge box for strain measurement is shown in Table 3-1.
The sensor cables between the data acquisition system on the measurement rack of the largescale separation shock test facility and a TS, or other measurement lines, check-out cables, etc.,
prepared by users, can be laid to the reverberation chamber outer-rooms, satellite path, etc., throughthe measurement relay unit or the feed-through hole next to the heavy door. Since no one can enter
the reverberation chamber outer-rooms during a test, the check-out device that belongs to a TS is tobe set in the satellite path (next to the heavy door.) Also, when using the feed-through hole, makesure to fill any clearance with clay, etc., after connecting cables through it, so that GN2 wouldn’t leakout during a test.
(1) Connection of sensors and cables
When measuring acceleration, attach acceleration sensors on a TS, and connect them tothe measurement relay unit and patch panel in the reverberation chamber using low-noise
cables.
When measuring strain, attach a strain gauge onto a TS, and connect it to a bridge box.
Use a 120.0Ω strain gauge, since this facility has no zero-balance function.
(2) Line checking
For verifying the test configuration, the connected measurement lines are to be checkedusing the oscilloscope function of an operation PC. That can be efficiently carried out when
TS users and AES work hand in hand. The operation PC can also check the noise of the dataacquisition system.
(3) Automatic range adjustment function of data acquisition system
The data acquisition system in this facility owns an automatic range adjustment function.
That is, it can automatically adjust a range by predicting the response peak level at the Full
Level state from the response level of each acceleration/strain channel at the Blow Noise state.
That function, however, is not possessed by the data acquisition system on the measurement
rack of the large-scale separation shock test facility.
First of all, the response RMS (rms level) at the Full Level state is calculated from theresponse RMS (rms level) of each acceleration/strain channel at the Blow Noise state basedon the assumption that acceleration/strain response RMS is in proportion to sound pressurelevel (equation 1), then multiplied by a factor C the way response peak levels can be23This may not be the latest edition.

enveloped (to avoid overload), to set a range (equation 2.) The factor C can be specified byusers (if not specified, “5” is chosen.)
The image diagram of the automatic range adjustment function is shown in Figure 3-9.

Note) As for the strain measurement channels, 3 channels make up 1 set (chs 3001 ~ 3003, chs3004 ~ 3006...) due to the functional restriction of the amplifier. That is, when users use
only 1 or 2 channels, bridge box(es) with the resistance of 120Ω will be connected to therest of the channel(s) by the facility-side personnel.

3.2.3 Facility Equipment I/F
The facility equipment consists of a TS dolly, microphone stands, etc.
The TS dolly, which consists of the main body, a raising jig, and a towing tractor, functions bothas a raising jig and a moving dolly. Its external appearance is shown in Figure 3-13. A TS (Max.
mass of about 4t) is mounted on the dolly, moved from the preparation room, etc., to thereverberation chamber, and set there. By using a TS dolly, a TS does not have to be suspended nor
relocated onto a jig in the chamber. The height adjustment and transfer of the raising jig are
performed using an electric jack and an electric towing tractor, respectively.
A raising jig is fixed onto the stainless plate in the center of the chamber floor with bolts (M20
× 12 pieces) to keep its rigidity. Its performance and specifications are shown in Table 3-3. A TS ismounted on top of the cylindrical raising jig (cf. Figure 3-14), whose TS I/F is made to fit the I/F ofan H-IIA launch vehicle, which allows an H-IIA launch vehicle PAF to be directly mounted on the
I/F.
In case a TS with other types of I/F is to be mounted on the raising jig, users are to have an
adapter manufactured on their own for each TS. (Use the M12 screw holes with diameters of 2,030
mm and 2,350 mm for fixing an adapter to the raising jig.)
The travelling and operation of the TS dolly with a TS mounted on it are to be performed byusers.
Microphone stands are to be fixed to the hole pattern positions on the floor shown in section
3.2.1. Microphones can be configured up to the height of 5m. The microphone stands can be bent
and used.

Execution of Tests

4.1 Test-related Work Procedure
A general flow of test-related work after carrying a TS into the Satellite Integration and Test
Building is shown in Figure 4-1. It generally proceeds as follows. Refer to the “Special Notes” insection 4.3 for the matters concerning the performance of tests.

4.1.1 Preparation for Test
(1) Users are to transport a TS to Tsukuba Space Center on a trailer, etc., and carry it into theSatellite Integration and Test Building through its two unpacking rooms. Users are to submit
necessary documents in the “management/procedure manual of Tsukuba Space Center (VAA2003003)” beforehand (likewise before carrying out a TS.)・ Unpacking room (1)dimensions of shutter: 8.3m (width) × 14m (height)
rated load of overhead crane: 20t
・ Unpacking room (2)dimensions of shutter: 8.3m (width) × 12m (height)
rated load of overhead crane: 5t(2) Users are to open containers in the fore-room, mount a TS on the TS dolly or a dolly preparedby users themselves, and transfer it to a designated assembly preparation room.
(3) In the assembly preparation room, test preparation, e. g., assembling of a TS, mounting of
sensors, etc., is to be executed.
(4) After completing the test preparation, users are to transfer a TS to the reverberation chamberand set it there. A TS dolly enables users to transfer and set a TS without dismounting it fromthe dolly as mentioned above; in other test configurations, however, (e. g., using a jig preparedby users, or suspending a TS, etc.), another dolly for carrying a TS is to be prepared by users
as well.
(5) The work in the reverberation chamber is to be limited to the least necessary (as little asmeasurement lines WBD, conductance check, etc.) Therefore, users are to complete
preparatory work that is required immediately before a test (functional test, loading ofsimulation propellant, pressurization, etc.) outside the chamber to the extent possible.
(6) After completing the WBD/continuity checking as well as visual checking of measurement
lines, users can conduct a test.

32

This may not be the latest edition.

4.1.2 Start of Test
(1) An acoustic test is started by blasting GN2 into the chamber from the GN2 system. The soundgenerated in the chamber at that moment is as high as about 115dB (Blow Noise level.)(2) While Blow Noise level is being loaded in the chamber, the response level of an acoustic test
is predicted from that of measurement channels, based on which the range of the dataacquisition system is automatically controlled to be appropriate. After controlling the rangeof the data acquisition system, data starts to be recorded.
(3) After the start of measurement is confirmed, the test-level sound pressure is loaded in thechamber using the electro-pneumatic transducer (viz. Full Level test.) A timer starts counting
when all the 1/1 (or 1/3) octave-band sound pressure levels reach the pre-set levels, and thetest is automatically finished when the pre-set test time has passed.
(4) It is also possible to set a Full-XdB test level as a Pre-level test before starting a Full Level
test. The load time and sound pressure level for a Pre-level test (viz. what level of dB is to be
deducted from the Full level) can be determined within the performance of this facility. The
shift from a Pre-level test to a Full Level test is achieved by automatic sequence.
(5) The maximum testable time of this facility is 10 minutes including the Blow Noise level phase.
It takes about 60 seconds to adjust the range of the data acquisition system during the Blow
Noise level phase (when the number of measurement channels = 232 chs (acceleration 200
chs + strain 32 chs)), and another 60 seconds to operate the sound generator to let it generate
the test-level sound pressure. Pay attention to the maximum testable time when setting thetest time for a Full Level test (or a Pre-level test.)(6) The measurement state of the data acquisition system can be displayed on the screen(oscilloscope screen) in terms of up to 36 chs per one screen by using the oscilloscope
function (multi scope display function) of the operation PC in the data acquisition system
during a test. (cf. Figure 4-2 for an example of the screen.)33

This may not be the latest edition.

4.1.3 Completion of Test
(1) The chamber is ventilated after finishing a Full Level test. The air inside the chamber isreplaced by the air in the satellite path. It takes about half an hour, while depending on the
acoustic test time, before the oxygen concentration in the chamber returns to the level whichallows the safe entrance by personnel. Until then, no one is allowed to enter the off-limits
area.
(2) While GN2 is being ventilated and replaced, the sound pressure control data is output fromthe computer in the sound spectrum control system (examples of output data are provided inAppendix B.) This data tells whether or not acoustic load of the specified sound pressure levelhas been applied for the specified time.
(3) The measurement results of a TS are to be analyzed simultaneously with (1) and (2) above. It
takes about 40 minutes after the end of a Full Level acoustic test to complete PSD analysis
and obtain results for 200 chs.
(4) A test is judged as having been completed based on the loading status of sound, themeasurement/analysis results of a TS, the visual inspection on a TS, etc.
(5) In case a retest is necessary, 1 ~ 2 hours (depending on test conditions, temperature/humidity
environment, etc.) are to be spared after the completion of a Full Level test to get the GN2
system ready. Also, the LN2 storage tank, which has a capacity for three times of acoustic
tests (again, depending on test conditions), may require filling if the residual amount is little.
(6) The removal work is to be started after a test is judged to have been completed. It is desirable
to carry out a TS from the reverberation chamber as soon as possible.
The period of occupying the reverberation chamber to pursue the series of work for a test isabout three days for a subsystem and five days for a system, even though it depends on the size of aTS, etc.

4.2 Designation of Test Conditions
Users are to submit the test conditions requisition sheet shown below so that an acoustic test canbe carried out smoothly without errors. Its format is in Appendix C.
(1) Test conditions requisition sheet(a) Fill in the “test conditions requisition sheet” with test/analysis conditions, and submit it
to us before a kickoff meeting. Its format and fill-out guidelines are shown in Appendix
C.
(b) Examples of analysis output are shown in Figure 4-3 (1/2)(2/2).
(c) All the measured test data (binary data) are written and saved in a DVD along with asensor database list (cf. (2) below.) The analyzed test data can not only be printed out but
saved in a CD-R in csv format, etc. An output example is shown in Appendix E.
(d) The types of applicable analyses are different depending on facilities (cf. “mainspecifications” in section 2.2.)(2) Sensor database list(a) Fill in the sensor database list with the measurement conditions for measurement points(the sensitivity information, ID, etc., of the sensor mounted on each measurement point),
and submit it to us before starting a test.
(b) A sensor database list is to be created in a Microsoft Excel file (Office 2000 or later
version.) following the specified format. The guidelines for creating a sensor databaseare shown in Appendix D.
(c) By creating the random vibration conditions for mounted equipment in the designatedformat, the random vibration environmental conditions can be superimposed on the PSD
analysis results of each measurement point. Examples of superimposing are shown in
Figure 4-3 (2/2.) The guidelines for filling out the designated format are shown inAppendix D.

Note) While we require a sensor database list to be created in an Excel file, please do not use the
LINK function of the cells.

4.3 Special Notes
4.3.1 Restrictions for Tests(1) Up to three tests can be performed per a day.
(2) A two-hour interval is required between tests.
4.3.2 Check on Measurement Lines
The measurement lines including those of sensors are to be checked thoroughly by tapping, etc.,
during the preparatory work.
The checking after the start of a test sequence is to be avoided as much as possible for the sake of
reducing LN2 consumption. In case it is necessary to check measurement lines during a test
sequence, use the oscilloscope function (multi scope display function) of the data acquisition system
to complete the task in a shortest time possible. Meanwhile, please refrain from checking
measurement lines during a pre-level test, with regard to the protection of a TS and smoothadvancement of a test sequence.

4.3.3 Acoustic Test Conditions for Large TS
When performing an acoustic test on a large TS, the difference of acoustic properties between thecases of an empty sound field and the actual test is to be taken into account for setting the control
target level or the abort level (especially in the low-frequency band.) Furthermore, the difference
between TS models can result in the error of over 2dB in the controlled results, depending on thetarget frequency bands of sound pressure controlling. To avoid overload on a flight model due tosuch errors, a low-level preliminary test is to be performed on it to check for the difference(s) from astructural model.

4.3.4 Wearing a Helmet
The observers, etc., for a TS are to wear a helmet (to be prepared by users) in the test room
during crane work and a test.

4.3.5 Cleanliness Control
The cleanliness in the test room is controlled to keep ISO class 8 (class 100,000) level. Users are
to wear a clean garment (to be prepared by users) when entering the test room.

4.3.6 Security Verification
The external recording media to be used for giving/receiving data, e. g., a sensor database list,
to/from this facility, are to be put through virus checking using software for that purpose before
application.
