Abstract: In this paper, Inspire software for the optimization and design of an arc support, mainly through the control variable method to explore the influence of different optimization scheme for curved support. Specially improved arc support frame structure, reduce material on both ends of the frame body, effectively solve the arc support raw material redundancy structure, lightweight significantly. For lightweight design provides a new train of thought and feasibility plan.

Key words: Arc support; Structure optimization; Light weight; Topological optimization; Inspire software

摘要： 本文应用 Inspire 软件对某弧形支架进行优化设计，主要通过控制变量法探索不同优化 方案对弧形支架的影响，特别改进了弧形支架架体结构，减少架体两端材料，有效地解决了 弧形支架原始结构材料冗余问题，轻量化程度明显，为轻量化设计提供了一个新的思路和可 行性方案。
