模块化CAD模型与有限元模型的数据交换
Data Exchange Between CAD and Finite Element Models in Modular Design

摘要: 提出了基于结构有限元静、动态特性分析的模块化设计的框架.针对模块化设计系统中CAD模型与有 限元模型数据相互传送难点,根据不同情况,给出了模型转换的实现方法:直接转换法、标准零件库方法和中心 数据库方法,重点讨论了利用中心数据库进行数据传送的具体方法.Abstract: A modular design frame based on the static and dynamic analyses of structures by the finite element method (FEM) was put forward. To overcome the difficulty in data exchange between a CAD model and an FE model in a modular design system, three approaches,i.e.simple translation approach, standard parts library approach and central database approach, were proposed for different applications. The concrete measure of data transmission using the central database approach was discussed particularly.
