摘要
工程结构优化设计，是将有限元等数值分析方法和数学规划等最优化方法结合起来、优选改进结构设计方案的一种先进技术，它使得工程师不再局限于凭经验和试凑的方法去设计，而是可以科学地高效率地选择最佳设计方案，因而也是结构分析和ＣＡＤ技术向更高层次的发展。本文介绍的ＭＣＡＤＳ是一个通用性的计算机辅助结构优化设计软件，它吸收了结构优化理论研究的成果并采用了面向工程结构设计的实用化技术，具备较强的功能和适用性，已作为商品化软件转让并在许多工业部门得到成功的应用．
he design optimization of engineering structures is an advanced technique to optimizestructural design,Combining numerical analysis methods, finite element and etc.,with opti-mization theories,mathematical programming and etc,the design optimization makes engi-neers be capable of selecting optimum design effectively on the basis of scientific computa-tions and out of experience and trial limitations. It is also the progress of structural analysisand CAD technologies. The MCADS introduced here is a general purpose package used forcomputer aided structural design optimization. The research achievements on structural opti-mization theories and practical techniques engineering design oriented have been employed toprovide powerful facilities and applicability.MCADS has been applied and sold in industries.
