摘　　要：行星框架作为行星传动机构的重要零部件,在设计时依然采用传统静强度设计理论,不能充分反映动载荷工况下的动态特征,导致工作过程中发生裂纹、突然断裂的现象,严重影响了行星传动机构的可靠性,给维修和保障带来很大的困难。因此对行星框架进行动态优化设计具有十分重要的意义。以行星轮数目为设计变量,采用基于接口的协同仿真技术作为求解工具,对某任务剖面下的行星框架进行动态结构优化,完善了行星传动设计方法,为设计部门提供有关寿命预测的参考数据。As the main part of planetary drive mechanism, planetary frame is designed still with the static strength theory. Because it can＇t reflect the dynamic loads, crack and brake will happen during working process which affect the reliability deeply and result in the difficulty to repair, so planetary frame＇s dynamic optimism is significant in practice. Being advanced simulation technology as an effective way to achieve the result of target function, the dynamic optimism of planetary frame was researched with principle of the minimum, and treats the number of planetary gears as design variable. The results supply not only theory basic to planetary optimism but also the quantified life data.
