摘要

结合有限元仿真模型分析铸造铝合金车轮轮辋断裂的原因

并对轮辋结构进行优化

提出了加大槽底夹角和增加部分轮辋壁厚的方案。此方案能使车轮通过下落高度为150 mm的90°冲击试验的验证

解决了车轮在使用过程中出现轮辋开裂的问题

为铝合金车轮前期设计开发提供参考。

Abstract

Combined with the finite element simulation model to analyze the reasons for the fracture of the casting aluminum rim

and optimize the rim structure

a solution to increase the bottom angle of the groove and wall thickness of partial rim was proposed. The scheme verifies that wheels can pass the 90° impact test with a falling height of 150 mm

and solve the problems of rim cracking during the use of the product

providing reference for the inchoate design and development of aluminum wheels.
