摘要
减震器塔是汽车上重要的承载部件,铝合金减震器塔是汽车上应用铝合金实现轻量化的典型之一。文章以某电动车型的钢制减震器塔为研究对象,开展铝合金减震器塔的设计,通过采用拓扑优化的方法,并结合压铸工艺约束,经过多轮优化,完成铝合金减震器塔结构设计。最终通过仿真分析和实物验证,铝合金减震器塔相对钢制减震器塔在性能不降低的前提下可实现45%的轻量化。
The shock tower is an important load bearing part of the automobile. It is one of the typical lightweight applications of aluminum alloy in automobile. This paper takes the steel shock tower of EV as the research object, carries out the design of aluminum alloy shock tower, and completes the structural design of aluminum alloy shock tower by adopting topological optimization method and combining with the constraints of die-casting technology and through multi-round optimization. Finally through simulation analysis and physical verification, aluminum alloy shock tower can achieve 45% of the lightweight relative to steel shock tower in the same performance.
