结构拓扑修改重分析算法在I-DEAS中的实现

Implement approach of reanalysis method for topological modification of structures based on I-DEAS

介绍了结构拓扑修改重分析方法在I-DEAS软件中的实现方法。基于I-DEAS开放求解体系结构,设计了重分析方法的框架,利用开放求解器提供的命令和矩阵操作方法完成重分析方法的程序实现。重分析方法重新利用保存在数据库中的矩阵计算结果达到减少计算量的目的。给出了重分析方法在大型通用软件中的实现方法,为理论方法研究向工程应用提供了一种快捷的实现途径。

The implement approach of reanalysis methods for topological modifications of structures was discussed based on I-DEAS.The frame of the reanalysis system was designed based on the open solution architecture of I-DEAS,and the commands and matrix operation methods were used to write the program of the reanalysis method.The matrices manipulation results stored in database can be reused to save the calculation time of the solution.The presented method provided the convenient way for applications of the reanalys...
