摘　　要：针对目前减速器箱体结构设计主要依赖工程师经验、开发周期长、材料冗余等问题,提出了一种适用于箱体结构优化的拓扑优化方法,解决了拓扑优化方法难以应用于箱体外部肋板结构的问题;将拓扑优化与箱体结构性能分析相结合,研究拓扑优化对强度、刚度、模态的影响,为后续箱体优化奠定了基础。结果表明:拓扑优化可以在减轻箱体总质量的同时有效改善箱体结构性能,并有效简化箱体结构,为进一步的NVH优化提供更多优化设计空间。In view of the problems that the structural design of reducer case mainly depends on the experience of engineers,long development cycle,material redundancy and so on,a topology optimization method suitable for the case structure optimization was put forward to solve the problem that the topology optimization method is difficult to be applied to the external rib structure of the case.The influence of topology optimization on strength,stiffness and mode is studied by combining the topology optimization with the analysis of housing structure performance,which lays a foundation for the subsequent optimization of housing.The results show that the topology optimization can reduce the total mass of the case,improve the structural performance of the case,simplify the case structure,and provide more optimization design space for further NVH optimization.
