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。
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.
