| Abstract: | The planetary gear train of fnrklift wheel side reducer was researched as an objective. Under the premise of satisfying design requirements, the objective optimization mathematical model was established based on muhi-objective of minimization diameter of ring gear , maximum center distance and maximum degree of coincidence. The Pareto optimal solution set was obtained by using the improved NSGA- II for optimization of multi-objective, and the optimal design seheme was determined by using the multi-attribute weighted grey target decision model. Tire optimization result shows that, application of the improved genetic algorithm is both effective and feasible, and provides a uew way tbr flu＇- ther optimization design. |
