3D Parameter Design of Solid Rocket Motor System Based on CATIA

摘要:

为了提高固体火箭发动机系统的动态交互能力,方便用户直观地了解固体火箭发动机的内部结构,结合CATIA强大的三维建模能力,完成了该系统中最重要的三维参数化设计；以VC++为编程环境,运用CATIA自动化对象编程(V5 Automation)提供的二次开发接口,实现了固体火箭发动机系统中的三维绘图模块,同时介绍了两种在VC框架内动态显示CATIA三维模型的方法；实践证明,该系统能够快速的确定固体火箭发动机外形尺寸、标志量等设计参数,为固体火箭发动机的初步设计提供有效的帮助。

Abstract:

For improving the dynamically interactive ability of solid rocket motor system, making it easy and visual for users to know the internal structure of solid rocket motor, combined with powerful 3D modeling capabilities of the CATIA, this system complete the 3D parameter design, which is the most important in it. Based on VC++ programming environment, using the secondary development interface provided by CATIA automation object programming(V5 Automation), realized the 3D drawing module in solid rocket motor system, at the same time, introduce two methods of dynamic display CATIA 3D model in VC framework. Practice has proved, this system can quickly determine the design parameters of solid rocket motor such as appearance size, logo, provide effective help for preliminary design of solid rocket motor.
