Cyclic time averaging for machine monitoring

摘要

The condition of a machine is monitored with cyclic time averaging, a technique of allocating vibration energy to particular sources in a complex signal. The cyclic time averaging method is directed at processing time-domain vibration data of the machine to produce an averaged time waveform over a selected cyclic time period. Utilizing cyclic time averaging, the systems and methods analyze machine vibration signals to detect and evaluate specific sources of enemy contribution to the vibration energy of the machine. It is not necessary to employ a triggering signal to obtain the averaged time waveform.
