摘　　要：以某混合动力耦合系统搭载的双行星排齿轮机构为研究对象,建立考虑行星架结构柔性的双行星排齿轮机构刚柔耦合动力学模型,对行星齿轮机构的啮合特性进行分析研究。在此基础上,结合齿轮修形理论,采用遗传算法,以啮合错位量最小、传动误差最小及改善齿面载荷分布为优化目标对行星齿轮机构进行微观参数优化,得出最佳齿轮修形组合。最后通过仿真实验验证了基于遗传算法的修形方案的可行性和先进性。In this paper,the rigid flexible coupling dynamic model of the double planetary gear mechanism with planetary carrier structure flexibility is established,and the meshing characteristics of the planetary gear mechanism are analyzed and studied.On the basis of this,combined with gear modification theory,genetic algorithm is adopted to optimize the planetary gear mechanism by optimizing the micro parameters of the planetary gear mechanism with the aim of minimizing the misalignment,minimizing the transmission error and improving the load distribution of the tooth surface.The feasibility and the advanced nature of the modification scheme based on genetic algorithm are verified by simulation experiments.
