| 摘 要： | 讨论了“积分型总极值”优化方法在二维多连域弹性体形状优化中的一个应用.具体计算了含椭圆孔的弹性有限板两边受拉伸时,为减少应力集中加入两个辅助孔的形状优化问题.通过优化设计辅助孔的位置和孔径以及中心孔的形状使应力集中明显降低.实例表明“积分型总极值”最优化方法具有约束处理方便、优化效果好和收敛速度较快的特点,适合于求解这一类形状优化问题.

| Abstract: | The numerical examples of shape optimization are presented by the Integral Global Optimization method. Stress concentration reduction in a plate with an elliptical hole is accomplished by introducing optimally sized and placed circular holes, and also by optimal designing of the shape of the center hole. Results show that the optimization method is reliable and effective. |
