中文摘要：

应用NX6．0对汽车前围加强板进行了拉延工艺设计，并用PAM—STAMP2G仿真软件对其进行了成形工艺的有限元分析。通过优化拉延模面结构、工艺参数，缩短了模具开发使用周期，减少了调模工作强度，提高了模具设计效率，达到了加强板拉延工艺设计的目的。

英文摘要：

The stamping-die for strengthening part of auto has been designed by use of NX6.0 and the stamping process has been analyzed by use of PAM-STAMP 2G in the text. By optimizing the die surface structure and parametric data, the accuracy of design and the feasibility of forming process have been improved. In this way, the time from design to work of the die has been reduced, as well as the die-adjusting working force. The efficiency of die design has been raised.
