Acceleration Pickup Frequently Asked Questions
Question number FAQ-1382
To convert the voltage signal from the acceleration pickup into speed and displacement.
I would like to derive velocity and displacement from acceleration data that has been analyzed through frequency analysis. If there is an easy method to do this, please let me know. |
If the frequency f and the acceleration amplitude A are known, the velocity amplitude V and the displacement amplitude X can be calculated using the following formulas.
A （m/s2）
V = A ÷（2πf） （m/s）X = V ÷（2πf） （m）
In the acceleration voltage waveform, conversion cannot be performed because 'f' is unknown.
Is there a method to observe acceleration waveforms recorded in data recorders as velocity and displacement waveforms? |
There is a method to obtain velocity V and displacement X through an analog integrator.
