| Abstract: | The application of cepstrum in compressor fault diagnosis was introduced in detail, which based on the character of compressor faults and the online-test system which was used to test the running compressor. We did spectrum analysis to the vibration signals. The special functions of cepstrum in testing cycle signal and side-band identification were fully proved by application. |
