摘　　要：本文对８５０ｘ３２０ｍｍ扁挤压筒内套进行了有限元分析计算，运用优化设计理论对扁挤压筒型腔进行计算机辅助形状优化设计，确定了使应力集中系数降为最小的最优形线，为延长扁挤压筒使用寿命提供了一条有效途径。The analysis and calculation of finite elements is brought about for u 850×320mm flat extruded cylindrical inner case in this paper.By applying optimization design theory the shape of the flat extruded cylindrical cavity is optimized with CAD,and the optimum shape lines are determined as the stress concentration factor is the lowest.Thus an effective way to prolong the life of extruded cylinders is offered.
