摘　　要：本文中将网格变形技术应用于某基础车型的改型设计中。根据拟定的变形方案,改变白车身有限元模型的几何尺寸,高效地建立新车型的有限元模型,并通过有限元分析对其性能进行预测。结果表明,网格变形技术避免了设计对详细CAD数据的依赖和费时的仿真准备工作,缩短了车型开发周期,降低了开发成本,真正体现了CAE引导设计的理念。per. Specifically, The mesh morphing technology is applied according to the morphing scheme worked in-white is changed to build the FE model for new car model to the retrofit design of a baseline car model in this pa- out, the geometric dimension of FE model for its body- efficiently, with its performance predicted by finite ele- ment analysis. The results indicate that with mesh morphing technology, the dependency of design on detailed CAE data and the time-consuming preparation activities for simulation can be avoided, with the lead time for car model development shortened and the development cost reduced, truly embodying the vision of ＇ CAE leads design＇.
