Résumé

With a typical rotary compressor as the research object,the discontinuity of low frequency noise caused by beat vibration of rotary compressor is studied in this paper. Based on theoretical analysis of beat vibration, the internal pressure pulsation components of the compressor are tested. At the same time, an FEM model is established to generate motor harmonics simulation and time domain signal of motor torque obtained by over the FEM simulation. The root cause of the beat vibration is studied, and related optimization schemes are developed. The test results show that the reduction of discharge pressure pulsation and improvement of motor harmonics are effective to reduce the compressor low frequency noise caused by beat vibration.
