带宽优化算法

OPTIMIZINING THE BAND WIDTH

对大型结构进行分析与优化设计时,经常遇到高阶的刚度矩阵,减少刚度矩阵的带宽,对于减少内贮,缩矩时间具有重意义,本文提出一种带宽优化算法,经大量算例表明方法简便,效率高,适用性强。

We often encounter the high rank matrix in the analysis and optimization of a large structure, The reduction of the band width of a stiffness matrix has an important significance for reducing the internal memory capacity and shortening the calculating time. This paper proposes a method of opbimizing the band width. Many calcu]ating examples have showed that the method is simple, effective and adaptable.
