Rotating machinery analysis is primarily concerned with signals relating to the rotational speed and its harmonics. Orders are harmonics of the rotational speed, and therefore evaluating orders can be critically important on many types of rotating machines. Typically order tracking and analysis is done on non-stationary data, such as a run-up or coast-down of a machine.

 

Basic order analysis is performed using a fixed sample rate and generating waterfall plots of frequency data versus speed. It is common to record the raw time signal and perform post processing on this measurement also.

4Q will help you implement your NVH task in the laboratory while developing a motor and will supply NVH testing module for the EOL.
