The finite element method (FEM) was employed to simulate the acoustic characteristic of the suction muffler in a refrigerating compressor, the effects of different structure parameters (clapboard, intubation and intake tube) on the transmission loss (TL) of the muffler were analyzed, the structural parameters were op-timized, and the acoustic characteristic of the suction muffler was enhanced effectively. The research achieve-ments could provide theoretical foundation for the optimization design of suction muffler in the refrigerating com-pressor.
