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。 Based on the Dynaform software, the parametric design method of automobile panel surface is discussed, including the design of stamping direction, process replenishment surface, pressing surface, drawbead and so on. The quality of the forming is judged by the simulation. Process parameters are optimized. The results show that the use of Dynaform software can quickly determine the appropriate blank holder force value, optimize the size and shape of the rough, help to improve product quality.
