| 摘 要： | 本文推导了反对称阻尼振动系统的动力约束子结构法，利用反对称阻尼性质避免了求解左特征向量，并在缩聚变换中增添速度约束模态以提高计算精度，加之充分利用管系的周期性，较大幅度地提高了输液螺旋管系振动分析的效率。

| Abstract: | A constrained dynamic substructure synthesis method for skew symmetric viscous damped systems is presented in this paper. The properties of the skew symmetric damping matrix are employed to avoid the solution of left eigen vectors from the adjoint eigenvalue problem. In reducing transformation the velocity constrained modes are added to improve the accuracy of calculations. As application, the proposed method has been successfully utilized in the dynamic analysis of spiral tube systems conveying fluid. |
