针对乘用车白车身样件开发周期长和制造成本高等问题，以东风本田某款SUV车型翼子板样件开发为例，结合产品结构特点，运用CAD/CAE协同手段，设计了可快速修正的参数化试制冲压工艺方案。通过AutoForm有限元迭代求解技术对试制冲压工艺方案进行了可行性验证。在试制冲压模具结构设计之前，对潜在的成形性缺陷进行了识别和对策。根据数值模拟结果和3D工艺模面，基于短工序化和轻量化理念，减小模具尺寸，简化模具结构，降低模具重量系数，取消导向、定位、压力源等标准件的使用，最终设计了低制造成本的试制冲压模具结构，经过调试快速试制出满足整车匹配要求的工程样件。结果表明，基于CAD/CAE协同的参数化试制冲压工艺设计可有效缩短白车身样件开发周期，并降低样件制造成本。

For the problems of long development period and high manufacturing cost for passenger car with body-in-white, taking the fender of a Dongfeng Honda SUV model as an example, combining product structural characteristics, a parameterized trial stamping process which can be modified rapidly was designed by the use of CAD/CAE collaboration, and the feasibility of trial stamping process was verified by finite element iterative solution technology AutoForm. Before the trial stamping die structure was designed, some potential forming defects were recognized and solved. According to the numerical simulation result and 3D die surface, and based on the concepts of short process and light weight, the size of trial die was minimized, the structure of trial die was simplified, the weight coefficient of trial die was reduced, and the standard component such as guide plate, location pin and pressure source parts were cancelled. Finally, the trial die structure with the low cost was designed, and the prototype parts that meet the requirements of vehicle matching were produced quickly through debugging. The results show that the parameterized trial stamping process based on CAD/CAE collaboration shortens the period of prototype part development and reduces its cost.
