摘要
本文介绍了车身覆盖件冲压成形动态仿真中的几何建模技术和建模过程中所使用的造型方法。指出了车身覆盖件产品模型与冲压拉延模模型之间的区别;分析了拉延模型面造型与仿真模型的关系以及拉延模造型对仿真计算结果的影响;另外从CAD模型数据交换角度出发,说明了数据转换在建模技术中也起着非常重要的作用,同时介绍了三种常用的数据交换标准。最后给出了桑塔纳2000型轿车前门外板凸模的造型。
The geometrical modeling technology in dynamic
simulation of autobody panels drawing and formative method used in modeling
procedure is present in this paper.The distinction between the product model of
autobody panels and the model of the die is pointed out.The die styling's relation to
simulation model and its influence on simulation result are analyzed.Moreovre,from the
viewpoint of CAD model data exchange,this paper interprets that data exchange performs
a very important function in modeling tech nology.And three data exchange standards
are introduced.Finally,the styling of SANTANA 2000 frontdoor drawings punch is
presented.
