。。。。。(In this paper, the multi-objective structural optimization design of torque converter is introduced with the application of genetic algorithm. The main optimization criteria are torque ratio, efficiency, permeability and a series of high efficiency. 16 variables are chosen as the main optimization parameters. Among them are: the core diameter and the cross section parameters, the blade angle and other core and shell. The range of values of these variables is obtained from the prototype analysis of the structure. A mathematical model based on multi streams is adopted. A torque converter ph410 is provided for hydrodynamic calculation. Provides a parameter sub optimal for the group used as a basis for further consideration of the results of these calculations. In addition, the influence of the range constraint on the optimization parameters is analyzed. The difference is great)
