基于Ansys子模型法，建立压力容器平面舱壁主构架与耐压壳体连接处肘板结构参数化模型，进行三角形肘板和弧形肘板的应力与疲劳寿命仿真分析。并在此基础上进行Ansys与Matlab联合双目标遗传算法优化计算，优化后的肘板结构质量大大减轻，疲劳寿命显著提高，本文方法可为此类结构的强度分析及优化设计提供参考。
基于Ansys子模型法，建立壓力容器平麵艙壁主構架與耐壓殼體連接處肘闆結構參數化模型，進行三角形肘闆和弧形肘闆的應力與疲勞壽命倣真分析。併在此基礎上進行Ansys與Matlab聯閤雙目標遺傳算法優化計算，優化後的肘闆結構質量大大減輕，疲勞壽命顯著提高，本文方法可為此類結構的彊度分析及優化設計提供參攷。

Basedonthesub-modelmethodofAnsys,thepaperbuildsabracketparameterized model which was welded at the joint of the main truss between bulkhead beam and pressure shell. The paper simulates the stress and fatigue life of the triangle and curved brackets. Applied genetic algorithms method with Matlab and Ansys software co-simulation, the paper bring out a practical optimization method of curved bracket truss. The optimized bracket′s capability of mass and fatigue life improved obviously,so the method could provides reference for intensity analysis and optimum design of the bracket connections.
