英文摘要：

Based on multi-parameter, multi-objective and multi-constraint of planetary gcarreducer, the optimization mathematical model was established. In addition, the analytic hierarchy process （AHP） was adopted to cahulate the weights of sub-objective functions. Genetic algorithm is used to slove multi-objective optimization of the reducer parameters. The example of calculating indicated that the optimal resuh is more rational than traditional design scheme in the earlier references. Genetic algorithm technique is proved to be effective and feasible in carrying out multiobjective optimization of reducer,it also has certain guiding significance to the optimization of planetary gear reducer.
