摘　　要：采用有限元方法对300 MN多缸薄板成型压机框架进行了应力分析,查看应力集中情况,并对容易产生应力集中的初始圆角进行局部优化,得出圆角最优变量值。再结合各种常见的过渡圆角结构,赋予变量参数,进行局部集中应力优化,找出最优过渡圆角结构,以改善压机框架应力集中的情况。Analyze the stress of 300 MN multi-cylinders sheet moulding press frame by finite element method and observe the situation of centralized stress;optimize the part of initial circular bead which easily makes stress centralized,as last,the optimized variable value of circular bead is concluded.Furthermore,with every kind of common transition corner structure,we give variable parameter to optimize centralized stress in part and find out the best transition corner structure,reaching the aim of improving the situation that stress is centralized.
