采用变密度法和折衷规划法建立了结构的多目标拓扑优化模型，并利用分析层级法确定了子目标权重。以“U”型结构为对象进行了多目标拓扑优化设计，得到了结构质量较轻的新结构形式。该方法可应用于结构的优化设计。

Based on the solid isotropic material with penalization method, compromise programming was put forward to establish model of multi-objective topology optimization, furthermore, by using the analytic hierarchy method to determine the weight of each sub-goal. As U carriage structure for object, multi-objective topology optimization is analyzed. A new design with light weight was obtained. The method provides reference for structural optimization design.
