| 摘 要： | 本文对具非对称粘滞阻尼的振动系统提出一种约束部件模态综合法。首先消除状态空间部件运动方程内不独立的界面位移与界面速度，然后以截断的约束部件复模态、位移约束模态及速度约束模态作为里兹基，减缩总体方程。文末以算例说明了方法的有效性。

| Abstract: | A constrained component mode synthesis method for asymmetric viscous damped systems is presented. The dependent interface velocity and displacement of component motion equation in the state-spaceform are first eliminated. The Ritz base which consists of truncated complex modes of constrained components, velocity constraint modes and displacement constraint modes is introduced to reduce the size of theglobal equation. Examples offered in the paper illustrate the efficiency of the proposed method. |
