摘要
针对多学科设计优化的需求,综述了几种常用的参数化建模方法。对卷弧翼火箭弹参数化建模的基本原理和实现步骤进行了详细说明。利用UG NX提供的API开发了参数化建模的内部和外部程序,可为空气动力学科计算提供几何模型和为弹道学科计算提供弹体标志量信息。
Facing the needs of Multidisciplinary Design Optimization （MDO）, several popular parametric modeling strategies are reviewed. The basic principle and realizing process to construct the Wrap-Around-Fins rockets＇ parametric 3D model are described in detail. Both of the internal program and the external program are developed on UG platform through the API functions. They can not only provide geometrical model for aerodynamics sub-discipline but also can offer mass attributes for trajectory calculation.
