Abstract:

Aiming at significance of the shape of scroll profiles in the machine design,the theory of variable wall thickness scroll profiles and its shape optimization methodology based on functional theory was presented. The restriction conditions for the optimization mathematic model were analyzed, including the wall thickness of scroll compressor, the maximal diameter of the moving scroll disc, the axial distance, the pitch of scroll profiles, the height of scroll disc and the revolution radius.A optimization mathematic model of variable wall thickness scroll profiles was built. And the shape optimization example of variable wall thickness scroll profiles was given. The excellent performance and favorable shape characteristics for scroll profiles are obtained.

Key words: scroll compressor, scroll profile;variation thickness scroll, optimized design, modeling simulation
