工程结构优化设计程序系统 SOPSA 研制及工程应用

Development of programming system(SOPSA)of engineering structure optimal design and its application in engineering

本文以ＡＤＩＮＡ作为结构有限元分析程序，采用解析灵敏度算法研制了工程结构优化设计程序ＳＯＰ－ＳＡ，介绍了解析灵敏度算法在结构优化设计中的实现过程和ＳＯＰＳＡ的功能特点，考例和工程应用实例表明，该程序求解效率高，实用性强，适用范围广。

Taking ADINA as the finite element analytical program of structures and adopting the algorithm of analytical seusitivity this paper developed an optimal design program of engineering structure(SOPSA).The realizing process of analytical sensitivity algorithm in the optimal design of structures and the functional features of SOPSA were introduced.Samples and examples of engineering application demonstrate that this program has high solving efficiency,strong practicality and wide range of suitability.
