近似方法在多学科设计优化中的应用研究

The Applied Study of Approximation Methods for Multidisciplinary Design Optimization

文中针对多学科设计优化中出现的问题,探讨了现有近似方法在 MDO 中的适用性。依据近似函数所能模拟设计空间的大小,将近似方法分为:局部近似、全局近似和中等范围近似。局部近似和中等范围近似在结构优化设计中应用广泛,全局近似(如响应面法)能够解决 MDO 中出现的问题。近似方法是处理 MDO 复杂性问题的有力工具。

This article has discussed how to solve the problem in the multidisciplinary design optimization with the approximation methods.According to their range of validity in the design space,tbe approximation methods can be divided into three categories:local approximation method,global approximation method and mid-range approximation method,local approximation and mid-range approximation methods are most common in structural optimization. global approximation method (response surface methodology) can easily solv...
