Abstract: A nonlinear mathematical programming model with multi-object for an optimal design system of centrifugal compressor was established and studied. The model has practical constraints of both aerodynamics and manufactory for effective applications. Its optimized variables are discrete and continuous. To solve the optimization problem the model was simplified and two new methods “mixed searching method” and “cost-benefit conformity method” were presented in the calculation. The optimal design system with computer program was developed by means of the simplified model and calculational methods mentioned above. After practical applications high successful benefit and satisfactory results have been obtained in Shengyang Blower Works.
