基于有限元的齿轮箱惰轮端面磨损分析

Analysis on Gearbox Idler End Wear Based on Finite Element

在齿轮箱设计中,惰轮端面磨损经常出现,本文通过有限元方法深入剖析了惰轮磨损的根本原因,即惰轮受到轴向力或径向力产生的倾覆力偶矩,与壳体端面产生应力集中,造成剧烈摩擦,并提出了三种适用于不同结构环境的解决对策,经试验验证效果很好,为变速箱、取力器、驱动桥中的惰轮设计提供理论参考,避免以往经验设计的随机性,提高了设计效率。

This paper aims at optimizing the structural parameters of a inclined leaf spring independent suspension. The parametrical CAE model of the leaf spring was established through ANSYS. And then the sensitivity analysis of key parameters, such as thickness and curvature, on the maximum stress of leaf spring was carded out. Considering the maximum stress is no more than 800Mpa, the structural parameters were optimized based on the objective that minimizing the weight of leaf spring.
