Résumé

In the noise and vibration test of the rotary compressor, the peak value of noise and the corresponding frequency can be identified according to the analysis of frequency spectrum. But it can not be obtained that the noise is in which rotation angle range according to the analysis of frequency spectrum, which can be obtained according to the equal angles sampling system. In this paper, the noise and vibration of rotary compressor under different operating frequency in angle domain can be measured using the multi-pulse method, which divides a working cycle into many equal angles. According to comparing the spectrum of noise and vibration of discharge stage and the one of the other stage, the main frequency range of noise and vibration of discharge stage can be obtained.
