近几年来 ,锻造形状优化得到了众多学者的关注。本文对单工序锻造问题的毛坯形状优化进行了研究。以毛坯高径比为优化设计变量 ,目标函数取为实际锻件超出预定理想直线部分的体积 ,以黄金分割法进行优化迭代 ,给出了目标函数的表示方法及计算表达式。并对一典型的轴对称H型锻件的毛坯形状进行了优化设计 ,取得了明显的效果 In recent years, forging shape optimization has attracted the attention of many scholars. In this paper, the optimization of blank shape for single-step forging is studied. Taking the ratio of blank height to diameter as the optimal design variable, the objective function is taken as the volume that the actual forging exceeds the predetermined straight line part, and the golden section method is used to optimize the iteration. The representation method and the expression of the objective function are given. The shape of the blank of a typical H-shaped forging was optimized, and the obvious effect was obtained
