优化方法在飞机翼面结构设计中的应用(为庆贺游兆永教授60寿辰而作)

The Application of Optimal Method in Wing Structure Design of Airplane

本文首先对飞机结构多约束优化设计系统I型(YIDOYU-Ⅰ)作一简单介绍,然后描述系统在使用WUMT方法中的一些主要技术措施:引入近似概念、近似分析技术以及约束的解析求导,以减少优化设计过程中需进行的完整结构分析次数、求导次数和每次的计算量,为飞机设计部门提供了一个实用、高效、可靠的大型应用程序系统。最后略谈系统的发展概况。

First of all, a brief introduction of an optimal design system of wing structure of airplane under multi-constraints (YIDOYU-I), and then some main measures of the system: approximate concept, approximate analysis technique and analytical derivatives for constraints to reduce the number of time consuming FE structural analysis, dcrivating and the amount of computing. It provides a practical, efficient, reliable, large-scale application program system for the airplane design department. At last a brief report of the development of the system is given.
