参数机制方法在工程型号中的实际运用

立足于飞机结构大部段,系统提出一种建模的参数机制方法。总结了当前基于参数化设计方法中的一些典型逻辑思路。通过对基本原理和规律进行析和对比,结合计算机三维建模的相关知识以及实际工作中反复的实践,建立了一套针对国产飞机的三维建模方法。该方法立足于成熟的商用平台CATIA,鲁棒性高、操作性强,填补了国产飞机设计阶段建模方法的空白,提高了飞机设计研发效率,通过实际运用,论证了该方法的可行性和实用性。

Engineering Application of Parameterized Design Method in Domestic Aircraft Project

A systematized design method based on parameterized method was established. This paper attempts to sum up the newest geometry logic control methods based on parametric technology in aircraft design and find some general principles and rules implied in these methods combining computer graphics theories. The high efficiency and controlled mechanism had been confirmed under fierce competition. This paper will help to enhance a fuller understanding of domestic aircraft design parameterized method by using CATIA, a commercial software. High robustness and good operability are its characteristics. By using parameterized method, design and producing process had been connected. The capability to enhance industry batch production in the domestic aircraft development stage had been proved by using this method. At last, the research work, having a broad engineering application, was prospected.
