| 摘 要： | 增加阻尼对结构振动抑制具有很重要的意义,为克服三维有限元建模单元数量较大的问题,采用整体单元方法求解圆形空心截面约束阻尼梁的拉伸、弯曲和扭转振动。分析结果同三维有限元分析结果作了比较,证明了该方法的可行性,为圆形截面构件组成的刚架和桁架结构约束阻尼层振动抑制分析提供了简单的计算方法。

| Abstract: | The augmentation of damping is the key to suppressing structural vibration.To cut down element number for modeling structure with constrained damping layer(CDL) in general FEM software,the whole element method is adopted to solve the extension,bending and torsion vibration of the hollow circular beam with CDL.The comparison between the analytical results and 3-D FEM ones shows the validity of this method for truss structure and rigid frame consisting of hollow circular beams with CDL. |
