Oscillations peak-to-peak amplitude value

Question 

In accordance with the test perfomance requirements it is necessary to maintain oscillation peak-to-peak value within certain range. Can this parameter be calculated and maintained by the vibration controller? At the screenshots available on your web-site I have seen three similar parameters: RMS, amplitude and peak value. Does the crest factor value parameter stand for the above-mentioned peak-to-peak value?

Answer

Yes, the Software application ““Sinusoidal vibration”” allows to control oscillations displacement constant amplitude (it is important to specify the particular parameter to be controlled since in the course of tests perfomance oscillations have acceleration, speed and displacement values).

“RMS” and “Amplitude” are methods for the control parameter measurement. In the case of all types of vibration tests there is a control of acceleration value. In order to avoid confusion in terminology, the value measurement methods are referred to as “Effective” and “Circumflexing”.
