Abstract: Scroll plates are the key parts of scroll compressor,and its assembly is critical and difficult to the whole assembly of machine,which involves a number of quality parameters.To reduce the impact of fluctuations on assembly quality,the assembly characteristics of scroll plates was analyzed,and a multi-objective integrated evaluation function for the minimum of radial and axial clearance and minimum mismatch rate was established,based on variance model.The computer aided selective assembly method based on genetic algorithm was designed.The experimental results were compared with the complete exchange method,and the result showed that the proposed method could solve the problem of scroll plate's assembly with multiple quality characteristic,and realize the minimum fluctuation of both radial clearance and axial clearance as well as minimize the surplus components.

Key words: scroll compressor, computer aided selective assembly, multiple quality Characteristics, genetic algorithm
