无限元与相同子结构串的一致性及其算法

AGREEMENT OF THE INFINITE ELEMENT METHOD AND THE ANALYTICAL METHOD FOR CHAIN OF IDENTICAL SUBSTKUCTURES AND THE SOLUTION OF TRANSLATIVE MATRIX

摘要: 讨论了无限元方法￣［１］与相同子结构串分析￣［２］的一致性，综合文［１］和［２］得到一种通用算法，依据文［３］尚可应用于ＬＱ控制问题，且提出一种直接求出转移矩阵的算法，具有简便和较高精度的优点．

Abstract: An agreement of the infinite element method and the analytical method for the chain of identical substructures is discussed in this paper.Ageneral solving program isgiven,which is based on reference1and2and can be applied to LQ control problems。Moreover,in this paper is the translative metrix X is solved directly by iderative method,which is very simple and accurate。
