摘要
本文用边界元法与序列无约束优化方法相结合,对平面应力下的弹性体进行了形状优化,在优化过程中,用虚拟目标法处理多目标问题。为避免烦锁的灵敏度分析,采用了“新单纯形方法”。文中作的例题,获得满意结果。
In this paper, the shape of an elastic body suffered plane stress is optimized by Boundary Element Method and Sequential Uneostrained Minimization Technique. In process of optimization, the multiple objective problem is treated by fictitious objective method. To aviod teaious sensitivity analysis, the 'New Simplex Method' is used and the satisfactory result of the example is obtained.
