The concept of equivalent cylinder diameter of scroll compressor is put forward, and the height, groove width and thickness of the profile line are divided into three independent dimensionless characteristic parameters.By analyzing the relationship between characteristic parameters and profile structure parameters and the characteristic parameters The analysis of the influence of compressor’s dynamic performance has obtained the changing trend of the axial gas force and the rotating inertia force of the movable scroll with the characteristic parameters. The trend of the two is similar: they decrease rapidly with the increase of tooth height coefficient Small, with the increase of the tooth thickness coefficient increases rapidly, which is less influenced by the groove width coefficient.Furthermore, the preferred range of the characteristic parameters is given: the tooth height coefficient should generally be in the range of 0 42 ~ 52 2, the groove width coefficient Generally, it should be within the range of 0 2 1 ~ 0 2 4, and the tooth thickness coefficient should generally be within the range of 0 0 4 ~ 0 0 6. The optimal strategy of the characteristic parameters under different design conditions is given
