摘　　要：以体积和频率作为约束,以各工况载荷下对应的最小柔度作为目标函数,采用带权重的折衷规划法和SIMP密度函数插值模型研究了多工况条件下客车车架结构多刚度拓扑优化问题。并以某三段式客车车架为研究对象进行了多刚度拓扑优化,得到了合理的车架拓扑结构。Multi-stiffness topology optimization for bus frame under multiple-loading conditions is studied with the minimum compliance as objective and the volume and frequency as constraints, based on SIMP interpolation scheme and weighted compromise programming approach. As an example, a three-segment bus frame is optimized with a reasonable topology structure of frame obtained.
