中文摘要：

在dynaform平台中对汽车油底壳进行前处理、数值计算、后处理设计,对拉深速度、压边速度、压边力等工艺参数进行了正交设计,并根据成形极限图和厚度云图对成形质量进行了分析,获得一组最佳工艺参数.该优化参数为实际生产中拉深出合格质量的产品提供科学依据,是提高生产效率和企业经济效益的重要条件.

英文摘要：

The automobile oil sump is designed through preprocess,numerical calculation and post-process on the dynaform platform.The process parameters,such as deep drawing speed,blank holder speed and blank holder force,are optimized through orthogonal design.Further analysis is carried out according to the forming limit diagram and thickness diagram.The work results in a set of optimal process parameters,which provide important guidance for drawing quality products in the actual production.It is a significant condition in improving production and economic efficiency.
