Abstract: At present, compressor noise source optimization has reached the bottleneck; therefore, the main direction of noise reduction of vibration is to optimize the noise transmission path. The compressor rubber pads are most important defense of preventing spread the compressor vibration source to the refrigerator plate and side panel, etc. It plays a vital role in preventing spread the noise. The paper optimizes the structure of the rubber pads from the two indexes of natural frequency and vibration isolation rate. The experimental results show that reasonable optimization of the compressor rubber pads can effectively avoid the compressor resonance zone and improve refrigerator noise and vibration.
