一种实用的工程CAD优化方法

A kind of practical optimization method in engineering CAD

本文针对工程ＣＡＤ中的混合离散规划问题，提出了一种迅速而有效的优化方法──改进正交试验法。该方法是一种直接优化方法，具有简单直观、对目标函数无特殊要求等优点，适合于既有连续变量、又有离散变量的复杂工程问题。大型变压器和感应电机的优化设计结果表明，该方法是一种实用、有效的工程ＣＡＤ优化方法。

irected against the problem of mined discrete plan in engineering CAD this paper put forward a kind of speedy and effective optinmization method-the improved orthogonal experiment method.This method is a kind of direct optimization method, it possesses the advantages of simplicity, audio-vistlalization and no special requirements to the objective function. It is suitable for complex engineering problems with both continuous and discrete variables. The result of optimization design for large transformers and induction motor indicates that this method is a kind of practical and effective optimization method for engineering CAD.
