基于CAD/CAE集成的导弹结构仿真系统

Development of a Missile Virtual Test System Based on CAD/CAE Integration

开发了一个基于工程数据库的CAD/CAE集成的导弹结构仿真系统,它以商用CAD软件和CAE软件为基础,通过对CAD软件进行二次开发,获取实体模型边界表示信息,并在计算分析模块中读入实体几何信息,完成模型的重建和有限元分析。在这一过程中产生的数据存储于模型信息数据库中,并以统一的用户接口连接各模块而建立该原型系统。文中使用一个实例证明了该系统是有效且实用的。

Based on engineering database, a CAD/CAE integrated design system is developed, which is constructed on top of the commercial CAD and CAE applications. In this prototype, the boundary representation of a model is caught by the more exploitation to the CAD application;the consequent data is stored in an engineering database. In this way, an advantageous access to the geometry information is reached.
