| Abstract: | Aiming at problems of large total mass, low fatigue strength and poor shift ride comfort of 404 P tractor gearbox gear train, a multi-objective parameter optimization mathematical model of gear train was established, which took the minimum gear total mass, the highest fatigue strength and the highest shift ride comfort as optimization objectives.A multi-objective optimization method based on NSGA-Ⅱ with elite strategy was proposed.Optimization design of gear train parameters was carried out based on Matlab optimization toolbox.Results showed that difference of optimization rate for gear train mass was 187.30%,difference of optimization rate for gear train fatigue strength was 85.27%,and difference of optimization rate for gear train shift ride comfort was 9.09%.Compared with traditional experience design, transmission performance of 404 P type hilly tractor was further improved. |
