面向轻量化的转向器支架拓扑优化研究
Study on the Topology Optimization of Lightweight Steering Gear Bracket
摘要
Abstract
Structural topology optimization is an effective approach to automotive lightweighting.In this research,high-strength and tough 356Y.1 squeeze-cast aluminum alloy is used to replace YL113 high-pressure die-cast aluminum alloy,and the final lightweight model of the 356Y.1 squeeze-cast aluminum alloy steering gear bracket is obtained through two rounds of topology optimization.The results show that,compared with the YL113 aluminum alloy steering gear bracket,the topology-optimized 356Y.1 squeeze-cast aluminum alloy steering gear bracket achieves a 32.2%reduction in overall structural weight while meeting the required safety factor.关键词
