摘要

基于i SIGHT多学科优化平台集成有限元分析软件Abaqus,针对密封壳体结构形状进行优化,将子模型技术、整体-局部优化策略、混合迭代优化算法以及样条曲线的参数化方法应用于密封壳体结构的优化中,大大的降低了单次求解时间,提高了整个优化流程的效率。优化后结构不仅减少了材料用量,而且对局部的应力集中有了明显改善,并通过试验对优化减重结果进行了验证,方法成功解决了给定重量指标下密封壳体结构所面临的强度问题,为日后大型航天器密封壳体结构设计提供了可参考的技术路线。

Abstract

Based on i SIGHT multidisciplinary optimization platform integrated finite element analysis software ABAQUS,the sub-model technology,global optimization strategy,hybrid iterative optimization algorithm and parametric modeling method of spline curve were used in optimization design of sealed-module structures,which greatly reduced the single-solving time and improved the efficiency of entire optimization process. The weight and stress of sealed-module structures are reduced significantly after optimized and the optimization result are verified by hydrostatic test. This method solves a problem of high stress of sealedmodule and provides a referenced technical route for optimization design of sealed-module in future.
