| 摘 要： | 将空间框架结构的振动作为波动来研究，建立结构的波动模型，并基于此模型对结构进行被动阻尼减振设计。阻尼单元和阻尼铰两种被动阻尼方案被用来增加结构的阻尼特性。根据波动分析的结果，一种迭代的方法被用于寻求多个阻尼单元或阻尼铰的位置。结果表明，波动模型非常适合于对结构的局部进行修改和分析。

| Abstract: | The vibration of three dimensional frame structures is studied as wave motion. A travelling wave model is constructed for passive damping vibration reduction. Two ways of passive damping, damping elements and damping joints, are studied, and an iterative approach to select damping positions is proposed based on the results of wave analysis. The results show that the travelling wave model is very suitable for local modification and analysis of structures. |
