The Dynamic analysis models of the airconditioner outdoor unit and the compressor refrigeration system are established by means of the finite element method (FEM). The modal analysis is carried out by ANSYS code. The impact of the piping on the compressors structural vibration using the rubber pads with different hardness is obtained. The natural frequency and vibration mode of the system are computed. Then the most suitable stiffness of the rubber pads can be used to reduce the compressors structural vibration. The vibration and noise of the pads with various stiffness are measured. The vibration velocity curves are plotted and the spectrum analysis is carried out. With the appropriate measures for forecasting the vibration and noise reduction, the design scheme may be more scientific, feasible and economic.
