摘要
以变速箱中一对啮合齿轮为研究对象,通过拓扑优化技术与参数优化相结合的方式对齿轮轮辐结构进行优化分析,得到轮辐的最优结构,并对优化方案进行可行性验证。结果表明:优化后方案在满足强度要求的基础上可有效减轻齿轮质量,降低齿轮转动惯量。该优化流程和方法通用性强,可推广到其他零部件的优化分析中,为零部件的优化分析提供了新的思路和理念。另外,拓扑优化和参数优化相结合能有效地提高优化效率,缩短优化周期,是一种行之有效的优化设计手段。
Topology optimization and parameter optimization were combined to optimize the gear spoke structure, and then the feasibility of the optimization solution was validated. It is shown that the optimized gear spoke satisfies the design requirement based on weight reduction and inertia decreasing. The optimization process can be applied to any components and this method provides new idea for part optimization. Besides, taking advantages of topology optimization and parameter optimization can increase efficiency and reduce optimization cycle which is a feasible method for optimization.
