摘要

以铝合金摩托车轮毂为例

用CATIA软件对轮毂进行了三维建模

利用ANSYS软件模拟了车轮旋转弯曲疲劳试验过程

并进行了结构优化。优化结果显示

轮毂疲劳强度设计安全系数从1.61降低到1.33

轮毂疲劳寿命从310万次降低到75万次

轮毂质量降低了6%

达到了减重的目的。

Abstract

3-D geometry entity of motorcycle aluminum alloy wheel was modeled by CATIA.The wheel rotating bending fatigue strength was estimated by the ANSYS software

and the structural optimization was conducted.The results show that

after structural optimization

the safety coefficient of fatigue strength design is reduced from 1.61 to 1.33

and the fatigue life of wheel is reduced from 3.1million times to 0.75 million cycles with the weight of the optimized wheel decreased by 6%

realizing the purpose of weight reduction.
