摘要 针对模型缩聚的SEREP方法,提出利用矩阵分解技术进行动力系统主副自由度的算法.该算法允许选择特定的位移分量作为主自由度,保留在缩聚后模型中,便于在模型缩聚后进行后续的动力分析. A method to select the master and the slave DOFs in finite element model of dynamic structures is provided by using matrix decomposition technique.By the method,one may choose some special displacement components as the master DOFs reserved in the reduced model.
