摘要
建立了弹性平面孔洞形状优化问题的数学模型,提出用边界元法分析结构,采用积分型总极值优化方法进行孔洞形状优化,目标为最小化孔边最大应力。实例表明,文中介绍的数学模型和最优化方法是可行的,计算简单,效果好,收敛速度相当快。
An effective optimal method for the hole shape optimization in an elastic plane is proposed. The boundary element method is used to analyse the structure and the Integral Global Optimization method is presented to optimize the hole shape by minimizing the largest stress along the hole boudary. Two examples are illustrated. Results show the efficiency of the optimal method.
