中文摘要：基于Dynaform软件，探讨了汽车覆盖件型面参数化设计的方法,其中包括冲压方向、工艺补充面、压料面、拉深筋等设计，并通过仿真模拟判断成形质量的优劣，再对成形工艺参数进行优化。结果表明，利用 Dynaform软件能快速确定合适的压边力值，优化毛坯尺寸及形状，有利于提高产品质量。
英文摘要：A method of parametric design for automobile panels based on Dynaform was discussed, which included the design of stamping direction, addendum, binder surface and draw bead. The forming quality was judged by numerical simulation, then the forming parameters were optimized. The results show that the proper blank hold force and blank dimensions and its shape can be quickly confirmed by Dynaform software, which is helpful to improve the forming quality of drawing parts.
