Unmatched Tire-Coupled Road Simulation From the Technology Pioneer

More than 45 years ago, MTS changed
vehicle structural testing forever with theintroduction of “four-poster” tire-coupledroad simulation technology.
By applying vertical forces through thetire of the vehicle, the MTS Model 320
Tire-Coupled Road Simulator made it
possible to provide actuator displacementsin the test lab that were nearly identicalto the profile of the original road surface.
With this came a new standard for vehicle
testing cycle time, repeatability andefficiency. For the first time, meaningful
tests could be conducted before roadload data became available, and whilevehicle changes were still in process.
We’ve been refining this technology eversince, continually adding new capabilities
to meet emerging industry demands.
Today, more test labs around the world
use the MTS Model 320 Test System than
all other tire-coupled road simulation
systems combined. The reason for this issimple. You won’t find a more versatile orproductive tire-coupled road simulator
anywhere else.

The Complete Tire-Coupled Simulation Solution

Whether you need individual components
or a turnkey solution, and whether you
require consultation on pit design, restraint
system configuration or another mounting
approach, MTS provides everything youneed to make the most of the MTS Model
320 test system.
Actuators

MTS Model 248 Actuators employ
hydrostatic pressure-centering bearings
for reliable high-speed operation underheavy side load conditions. A largediameter, one-piece, chrome-plated
piston rod provides superior strengthand lateral stiffness, and the thick-walledcylinder provides high rigidity andtransverse resonant frequency.
Close-Coupled Accumulators

MTS close-coupled accumulators optimize
system transient response performanceby minimizing the physical length of theoil column between the accumulators andservovalves. This efficient design facilitatessuperior simulation of transient events
such as pothole strikes, and enables the
movement of hydraulic fluid using aless-expensive, lower-flow-rate hydraulicpower unit (HPU).

Servovalves

Hydraulic Power Units (HPUs)

Precision-engineered MTS servovalvesprovide high-flow, quick-response andlow-distortion performance. They areavailable in either a low-velocity, twostage configuration for less demanding
applications such as squeak and rattle
testing, or in a special three-stage,high-velocity configuration for efficiently
moving high volumes of oil to meetdurability testing demands. For maximum
testing flexibility, you can also easily switch
between two- and three-stage servovalves
on your MTS Model 320 test system.

MTS SilentFlo™ HPUs are renowned fortheir superior performance, compact
footprint and extremely low noise. They
are so small and quiet, in fact, that theycan easily be installed almost anywhere
in your laboratory. SilentFlo HPUs are
up to 30 dB(A) quieter than conventional
HPUs, and a “wall-hugging” design
requires minimal floor space. A variablevolume pump design also helps to optimize
energy-efficiency.

Structural Durability Testing

Today, laboratory simulation testing is acommon approach to fatigue and durability
tests around the world for the evaluation of
platforms, components and subassemblies.
The MTS Model 320 test system provides anideal solution for accurately and efficiently
performing baseline structural tests onearly vehicle prototypes.
By integrating laboratory testing into thevehicle development cycle, your test lab
will have a powerful means of improving
product reliability, performance andquality, while reducing costs and overallvehicle development time.
Add flexible and easy-to-use MTS cRPC
Pro software to optimize testing accuracy,efficiency and repeatability. In addition,
adapting to a variety of wheel sizes is quick
and easy with integrated MTS wheel pans
and restraints.

End-of-Line Production Quality Testing

The MTS Model 320 test system is an integral component of the
MTS First Road End-of-Line Test System. The First Road test
system is designed to operate in a controlled, repeatable test lab
environment — as opposed to the costly and non-repeatableproving ground, where discovery is costly and can be compromisedby such variables as driver behavior, wind noise and weather
conditions. Test control is achieved with the advanced MTS
FlexTest controller, working in tandem with MTS First Road
software specifically designed for end-of-line test applications.
With the MTS First Road test system, you simply drive a vehicle
on the test rig to accurately subject it to your choice of simulation
profiles. Simply push a button on the remote to activate yourtest sequence.
P O WERFU L A PP LICATION SOF TWAREThe MTS First Road test system is powered by application
software specifically designed to optimize the efficiency of
end-of-line testing. A highly intuitive user interface makes
it fast and easy for operators at all skill levels to set up andrun tests, while having the flexibility to easily switch between
test inputs.

Ride Comfort Testing

As ride comfort becomes increasingly
important in vehicle designs, manufacturers
are finding a greater need to compare theperformance of their vehicles against thecompetition, and to monitor the effects ofparameter changes. Subjective evaluations
from the driver and passenger are nolonger sufficient.

Flexible and user-friendly MTS cRPC Pro
software includes an application focused onride comfort evaluation to meet the ISO
2631 standard. Custom weighting functions
can also be applied with outputs presented
automatically in a simple summary report.

The MTS Model 320 test system adds
tremendous accuracy, repeatability andsimplicity to evaluating ride comfort.
Rather than performing evaluations ofseveral vehicles traversing the same
surface on the proving ground, you canreproduce exactly the same surface
repeatedly in the test lab, and several
vehicles can be quickly driven on and off
the test rig for quantitative measurements.
Engineers are also able to observe under
the car for direct evaluation of various
suspension elements.

Buzz, Squeak and Rattle Testing

Vehicle buzzes, squeaks and rattles wereonce perceived as unimportant. Today,
they have become a primary indicator ofvehicle quality to both manufacturers
and consumers.
Temperature, humidity, vehicle age andload environment all influence the amountof buzzing, squeaking and rattling. By
installing the MTS Model 320 test system
in an environmental chamber, you have an
excellent means of efficiently monitoringthese sound levels under various conditions
as the vehicle degrades. Standard waveforms
can be applied while the investigator isinside the vehicle and making note ofnoises heard and their likely sources.
For added convenience, an infrared remotecontrol is available for users to selectspecific test profiles.

O PT IO NA L SW IT CH A B L E F L O W L IM IT E R

A switchable flow limiter allows your system
to be used for both durability testing andbuzz, squeak and rattle evaluation. The
valve accommodates the high flow rates
required to reproduce the punishing forces
to fatigue the vehicle, and switches to thelow flow rates to detect the resulting squeaks
and rattles.
Q U IE T T E ST SYST E M O PE RAT IO N

The MTS Model 320 test system features a
low-noise design that allows you to precisely
evaluate the buzzes, squeaks and rattles
coming from the test specimen. That
includes wheel pans that are coated witha damping material to minimize noisetransmission to the test cell, and soundenclosures that confine noises created by
the actuator and servovalve operation.
Hydraulic line tamers minimize bothmechanically coupled and audible noise.

Racing Vehicle Development

You can accurately simulate racing vehicle
dynamic performance by adding threeor four downforce actuators to the MTS
Model 320 test system. These additional
channels allow the heave, pitch and rollof the vehicle to be controlled to low
frequencies, while precisely simulating
aerodynamic loading effects on the vehicle.
You can use this “seven-poster” simulation
rig to determine a wide variety of vehicle
performance attributes. Tests such as
full-vehicle spring rates and roll stiffness
can be completed with ease. You canalso conduct critical dynamic testing
to maximize traction, control chassis
dynamics and perform clearance testingfor best aerodynamic performance, alongwith in-depth analysis using cRPC Pro
application software.
High-Performance Downforce Actuation
Single-ended, double-acting MTS
Downforce Actuator Systems feature
remarkable passive compliance, whichis accomplished by using accumulatorsin the control ports. Other downforce
actuator performance advantages include:» Polymer hydrostatic bearings that help
to minimize frictional losses.
» A low-friction, low-pressure seal anddrain line that eliminate the need fora scavenging pump.
» A built-in bell crank in the fixture
assembly that matches the actuatorcapability to typical loading
requirements, presenting minimum
mechanical inertia to the test specimen.
» A tubular aluminum feedback loadcell built into the system’s lightweight
carbon-fiber strut, enabling
servohydraulic control of theoutput force.
» A DC-coupled accelerometer at the
specimen attachment point to support
reporting functionality and further
control enhancement.

Feature-Rich cRPC Pro Software
MTS cRPC Pro software enables thesimulation of racetrack data to be
performed on the seven-poster rig. By
instrumenting the vehicle to collect trackdata and combining this information withaero maps generated in a wind tunnel, you
can perform a highly accurate simulationof a racing lap in your test lab. Changes may
then be made to the vehicle to improve
the setup for a given portion of the track(bumps, curb strikes, mid-corner, etc.).
Aero-Mapping Capabilities
This calculated control technique can beused with downforce actuators to simulate
aerodynamic input into the vehicle affecting
body position, resulting in highly accurate
simulation of racing conditions.
Wide Variety of Wheel Pans and Restraints
MTS offers a wide variety of wheel pans
and restraints systems for easy drive-on/
drive-off test article installation andchangeover.

MTS MPT™ Software

Amplitude Phase Control Compensation

Easy-to-use MTS MultiPurpose TestWare®
(MPT) software offers powerful test design
and automation capabilities to help you
test at peak productivity. You can quickly
create your own test sequences, including
any combination of command generationand data acquisition. New test requirements
can be satisfied in a few minutes bydesigning a new test and saving it for
future use. You are not limited as you
might be with fixed-function generator
application. Other useful tools include
those for waveform generation, dataacquisition, event triggering, external
device control and more.

Amplitude and Phase Control (APC) is acompensation algorithm that monitors
feedback from sine and sine-tapered
commands, and adjusts the command
to correct for any error. This powerfulcapability can help you more accurately
meet the amplitudes and phase relationships
between channels in block cycle tests.

Adaptive Inverse Control Compensation

Adaptive Inverse Control (AIC) is anadaptive compensation technique that
automatically adjusts the command signal
to achieve the desired response signal.
AIC is used to improve test accuracy forvariable amplitude command signals suchas random and RPC drive files.

10

Trend Monitoring

This control capability allows you tomonitor changes in a test specimen
during a test, by periodically measuring
data from transducers attached to thetested part. This data’s statistical properties(maximum, minimum, mean, RMS andvariance) are logged and then compared
to a reference. If a statistic has changed
drastically from its reference, the process
can perform any number of user-specified
actions, including logging a message or
stopping the test.

Fatigue Monitoring

Calculations

Fatigue monitoring tracks changes in a test
specimen during a test by measuring datafrom transducers attached to the tested
part on a regular basis at specified points
in a long-term test. A rainflow analysis
is done on each data set to calculate adamage number. This number is logged
and compared to a reference. If damage
has changed drastically from its reference,
you can then either log a message or stop
the test. Fatigue monitoring also calculates
and logs accumulated damage for all thecollected data sets.

The FlexTest calculation control featureenables users to easily define calculations
from input signals. Several available mathfunctions exist including: +, -, x, /, cos,
exp, In, log, power, sin, tan and time. You
can even use one defined calculation within
another calculation.
CAN Bus Support

FlexTest CAN (Controller Area Network)
Bus Interface provides you with theflexibility to integrate a wide range of

CAN devices into a test. The flexible
MTS Series 793 software interface allows
both inputs and outputs to and from CAN
devices to be easily configured.
Time History Playout
This capability allows you to drive a test
system with an RPC time history file. This
gives you the benefit of playing pre-recorded
time history files without purchasing thefull suite of cRPC Pro software tools.

11Component cRPC Pro Software

When you use Component RPC Pro(cRPC Pro) software with your MTS
Model 320 system, you’ll be putting theindustry’s most powerful simulation andanalysis software to work in your vehicle
test lab.
At the beginning of the Remote Parameter

provides you with information about
your vehicle operating environment. This
information can provide critical details
about the character of your test article’s
performance.

12

You can use cRPC Pro software to replicate
the acceleration of a vehicle spindle bycontrolling the displacement of the tire, or
you can reproduce the strain on a part bycontrolling the force on the part, and manyother component testing applications.
RPC laboratory testing makes it easier foryour design and product engineers to see
firsthand the environment to which theircomponents are subjected, and the specificnature of any failures that occur.

You’ll discover cRPC Pro software to be as
intuitive as it is powerful. It includes many
helpful features to guide the novice user,
making the software extremely easy to learn
and use. User-friendly features include:» Preconfigured templates» Interactive wizards» Graphical displays» Integrated data management» Online context-sensitive Help

Wheel Pans and Restraints

Maintaining the vehicle on the test system
without introducing unrealistic horizontal
forces is always a challenge. After years ofrefinement, MTS has arrived at a restraint
system that has proven itself in this regard,in a full range of vehicle applications.
Standard wheel pan designs for the MTS
320 test system include:» 432 mm (17 in.) with restraint» 432 mm (17 in.) with bump
» 635 mm (25 in.) with restraint» 635 mm (25 in.) with bump
Both wheel pan sizes are also available with
Constraint Layer Damping (CLD).

Downforce Actuation Packages
You can simulate vehicle dynamic
performance by adding three or four
downforce actuators to the MTS Model
320 test system. These additional channels
allow the heave, pitch and roll of the vehicle
to be controlled to low frequencies. You
can also simulate aerodynamic loading
effects on the vehicle.
While this “seven-poster” configuration
is most often used with racing vehicle
structural testing, it can also be used todetermine a wide variety of performance
attributes for any vehicle type. For example,
tests such as full-vehicle spring rates androll stiffness can be completed with ease,and you can conduct critical dynamic
testing to maximize traction and control
chassis dynamics.

NOTES:			
1 Rated force is determined at 2800 psi differential across the piston.
2 Performance is measured at the wheel pan. Performance is not representative of spindle motion.
For performance estimations at the spindle see below tire magnification factors (valid near wheelhop frequency):
Passenger car: 2.0 to 2.5
Truck:
1.25 to 1.5
3 Static Support is used to zero out the mean load resulting from the sprung and unsprung masses so that actuator force is available solely for acceleration forces.

Worst case for all systems is for an actuator supporting 30% of total vehicle weight.
5 HPS sizing assumes average flow requirement is 25% of peak flow and HPU is operating at 50 Hz. This is only an estimate. More exact requirements can be determined by 		
analyzing customer’s drive files, if available.
