摘要
针对计算结构动力学和大系统理论所要处理的动态系统提出了一种模型降维直接迭代法,这种方法运算操作简单,不必计算系统的特征对,所以对系统矩阵的性能要求不高,有适用范围广,逼近精度高的特点。
This paper presents a direct iterative model reducing method on the dynamic system formed in computational structure dynamics and large scale system theory. The operations of this algorithm are very simple and it is not necessary to calculate the eigenpairs of system matrix, so this method relaxes restrictions on the property of system matrix. It has extensive applications and high approximating degree.
