Analytic Sensitivity Analysis for Shape Optimization
-
摘要: 在形状优化设计中,建立了边界元的全解析敏度分析技术,并将该技术与通用的形状优化设计算法相结合,对二维平面应力下的弹性体进行形状优化。在优化该文的例题时,用加权求和法处理该例题的多目标问题,最后获得满意的结果。Abstract: Analytic sensitivity analysis technology for the boundary element method(BEM)is presented,combined with a shape optimization system for structural analysis.A shape optimization was done for an elastomer under planar stress,based on this new algorithm.A multi-object problem was studied as an illustrative example for the programmer,using weighted summing method.The result is feasible.
