测量造型技术在汽车覆盖件成形数值模拟中的应用

Research of Measuring Modeling Technique Used for the Numerical Simulation of Autopanel Stamping

汽车覆盖件冲压成形数值模拟需要有精确的曲面CAD模型来划分有限元网格，利用测量造型技术从覆盖件产品的原模型获得CAD模型，并在此基础上建立成形数值模拟所需有限元模型的全过程，讨论了其中的关键技术和难点。

The precise surface CAD model is the base of the numerical simulation of autobody panel stamping. In this paper, the whole process of the applicant of the measuring and modeling technique on numerical simulation of autobody panel stamping is described. Also the key techniques are presented.
