| 摘 要： | 为控制大跨度斜拉桥拉索的大幅振动，研究了应用高阻尼橡胶剪切型阻尼器进行拉索减振，利用高阻尼橡胶剪切耗能优于挤压耗能的特性，提出了一种简便可行的外置式拉索减振器的设计方法；讨论了减振器刚度、安装位置、橡胶材料、拉索长度等参数对减振效果的影响；最后将其与粘性剪切型拉索减振器进行了比较。结果表明，高阻尼橡胶剪切型减振器具有更好的减振性能。

| Abstract: | In order to control the large amplitude vibration of cables of cable-stayed bridges, a shearing damper with high-damping rubber is developed. It has good shearing capability over the press one in energy dissipation.Its damping effects, damping rigidity, installation, rubber capability, length of cable are discussed. Its damping effects is compared with viscous shearing damper. The results show that it can more effectivelly control the cables vibration than viscous shearing damper. |
