为了提高发动机悬置支架的结构性能和减轻质量，以发动机悬置在多工况下加权柔度最小化和频率最大化为目标，并考虑了工程约束条件，对支架结构进行多目标拓扑优化。根据优化结果设计出的新发动机悬置满足强度、耐久性和模态频率的要求，降低了开发风险，减少了实物试验，节约了开发成本。
為瞭提高髮動機懸置支架的結構性能和減輕質量，以髮動機懸置在多工況下加權柔度最小化和頻率最大化為目標，併攷慮瞭工程約束條件，對支架結構進行多目標拓撲優化。根據優化結果設計齣的新髮動機懸置滿足彊度、耐久性和模態頻率的要求，降低瞭開髮風險，減少瞭實物試驗，節約瞭開髮成本。

In order to enhance the structural performance of engine mount bracket and reduce its weight, a multi-objective topology optimization on bracket structure is conducted with minimizing its weighted compliance and maximizing its natural frequency under different working conditions as objectives and considering engineering con-straints. The new engine mount designed based on optimization results meets the requirements on strength, durabili-ty and modal frequency, lowers development risk, reduce real component tests and cut down development cost.
