提出了一种用于拓扑修正的结构模态再分析的自适应迭代算法。给出了适应规则。该方法基于矩阵摄动，易于在计算机上实现。计算量很小，这对于随着关节和自由度的增加而进行拓扑修改是非常重要的。为了说明该方法，给出了三个算例。结果表明，该方法对拓扑修改的结构模态再分析是有效的。版权所有©2002约翰威利父子有限公司
An adaptive iteration algorithm is presented in this paper for structural modal reanalysis of topological modifications. The rules of adaptation are given. The method is based on matrix perturbation and can be implemented easily on the computer. A little computation effort is involved, which is very important for topological modification with the increase of the joints and the number of degrees of freedom. In order to illustrate the method, three examples are given. The results show that the proposed method is effective for structural modal reanalysis of topological modifications.
