Vibration technical guide1 Vibration terminology

3 Types of vibration
Principle of vibration

Vibration means the state of an object moving
repetitively back/forward, right/ left or up/down
and is generally expressed by Frequency,
Displacement, Velocity, and Acceleration.
These 4 elements are generally denoted as F, Ｄ,Ｖ,Ａ.
This is illustrated simply as a spring and mass.
When the mass is pulled down from the start
position and released, the mass moves just likethe vibration waveform shown in the graph on
the right.

Vibration can be divided into three types based on human perceptions; slow motion and visible
invisible but sensible by touching and insensible by touching, but audible as abnormal noise .

Displacement（D)Frequency means the number of times that vibrating
object generates a repetitive motion in 1 second.

Displacement means the amplitude (distance)
between the peaks of vibration.

Unit：μm, mm

Acceleration means the changing rate of velocity(V)to time

4 What is FFT ( Fast Fourier Transform ) ?

2 Measurement functions
These are the means to express the vibration in absolute value basing upon the waveforms measured
by the modes shown above.
1. PEAK（Peak amplitude）

2. rms(Root Mean Square value）

Peak value in a certain time duration.
It is used to measure shocks or waves which are rather
stable.

Root mean square value of the instantaneous values in a certain time
duration. It relates to the power of the wave. The rms value ofvelocity is one of the important factors for machinery status diagnosis.

FFT is one method of analysis, based on vibration waveform. Generally, waveforms are complicatedand diﬃcult to analyze. In FFT, we break waveforms down into a series of discrete sin waves, (left chart）
and evaluate each individually. (right chart)

PEAK to RMS ratio
It is used to determine deterioration of bearings
by relative comparison.

It is a sine peak assumed by the rms value.
For Sine wave, the relationship rms×√2=PEAK is valid. For avibration monitoring system, there is a case that EPQ ismonitored instead of the peak value avoiding to trigger theerroneous alarm by any accidental signal.

Mechanical failure is directly linked to stop of operation

Mechanical failure may cause a decrease of production

D: Low value machinery

Mechanical failure may cause inconvenient for operation

Mechanical failure is not linked to operation andrepair/replacement is much cheaper(Small general purpose motor etc.）2What is simple diagnosis?

The aim is to diagnose facilities and clearly show the degree of deterioration by measuring
vibration. Judgment value will be needed for precise evaluation. There are three main judgment
methods in simple diagnosis. Using these three methods will ensure more accurate measurement.

1. Absolute value judgment

Facilities are classiﬁed into several types (small type, medium type, large type). It is a method that if measured vibration
exceed a certain level , it is diagnosed as abnormality.

Advantage

Judgment is easy because diagnosis
standard is already established.

Chapter3
9Disadvantage

Vibration technical guide

Judgment may change depending on types orparts of facilities and makers.

Judgement example
ISO vibration evaluation standard

ISO 10816-3:2009 Vibration Standard Evaluation

This standard is widely used for synthetic judgmentof rotational machinery.
The current ISO standard 10816-3：2009
describes the absolute value judgment by velocity rms

Velocity severity (mm/s RMS)

2. Relative value judgment

The method of setting up the standard velocity RMS value and comparing the normal value with some absolute values
for judgment. Normal value of velocity RMS which is originally set up by someone is multiplied by x times to be
regarded as alert value or dangerous value . For example, when the velocity RMS value of motor shows 5.00 mostof times after more than ten times measurement, 5.00 can be set up to be the normal value. 10.00 (two times as highas normal value) is set up to be alert value, 25.00 (ﬁve times as high as normal value) is dangerous value. The normal
value should be decided after more than ten times measurement.

Advantage

More precise than absolute value judgment

Judgement example

Disadvantage

What is precise diagnosis?

The aim is to analyze waveform with FFT and identify machine part that have deteriorated withfrequency distribution, producing more reliable results than simple diagnosis. When a normal
machinery and an abnormal machinery are compared with FFT, it may show a big change at a feature
frequency value. The following chart is about the feature frequency and the kinds of abnormal state.

Because the normal value is decided according
to each personal experiences, so ambiguity
remains in the validity of the judgment values.

3. Intercomparison value judgment
A method of judgement by comparing vibration amount at the same measuring point of the same machine. If numericalvalue is more than twice as big as equivarent facilities, there is a possibility of abnormality.

Advantage

More precise than relative value judgment
