摘要
分析了轮辋结构对轮毂强度冲击试验的影响，将拓扑优化理论与实践相结合，在工艺条件不变的情况下，通过对轮辋结构的优化提升轮毂轮辋的强度，使轮辋应力集中相对分散，减小了外力冲击引起的轮辋变形量，提高了产品质量，进而降低了车辆在行驶过程中由于外力冲击引起的交通事故，大大提高了车辆的安全性和舒适性。
The effect of rim structure on impact test for wheel was analyzed. Combining the theory of topology optimization with practice, the strength of wheel was enhanced through the optimization of the rim structure at the same process conditions, and the stress concentration of rim was decentralized relatively to decrease the rim deformation caused by external shocks. The product quality is improved to reduce the traffic accidents due to external shocks in vehicle traveling process, and the safety and comfort of vehicle can be improved greatly.
