先进优化设计技术对参数化建模技术及参数化模型驱动技术提出了更高的要求。研究了CATIA参数化建模技术和二次开发技术，给出了以VB．NET为平台，采用CATIA的CAA Automation二次开发接口开发参数化模型驱动程序的方法，为先进设计优化技术的一项关键技术提供了一种实现方案。最后，运用该方法开发了某导弹的参数化模型驱动程序。结果表明，采用该方法开发的驱动程序完成一次导弹参数化模型更新仅需数秒时间，完全满足先进优化设计技术的需求。

On Driving Technology of Parametric Missile Model Based on CATIA

Advanced MDO technology requires more reliable parametric modeling and parametric-model-driv- ing technologies. Parametric modeling technology and second development interface of CATIA are studied, and the method how to develop parametric-model-driving program based on the VB. NET platform using CATIA CAA Automation second development interface is presented, so one key technology of Advanced MDO is carried out. At last,a driving program for a parametric model of a certain kind of missile is developed. The results prove that the driving program can update one parametric model in only few seconds, which can fully satisfy the need of advanced MDO.
