| 摘 要： | 利用高阻尼橡胶剪切耗能优于挤压耗能的特性,开发了一种外置式高阻尼橡胶剪切型拉索阻尼器对拉索进行减振控制。利用DASTLab5.0系列软件平台对拉索-阻尼器系统进行振动控制试验。试验工况分别考虑了有无阻尼器、阻尼器刚度、阻尼器安装位置等对振动控制效果的影响。试验结果表明:该阻尼器设计方法可靠,安装阻尼器后拉索阻尼有了很大提高;频率对阻尼器减振性能的影响很小;阻尼器安装位置对拉索减振效果影响很大;刚度一定时对橡胶构件的面积和厚度需进行合理取值;高阻尼橡胶剪切型阻尼器具有较好的制振效果。

| Abstract: | A shearing damper with high-damping rubber was developed to control the stay cable vibration,using the high-damping rubber shearing capability over the press one in energy dissipation.Based on the DASTLab5.0 software system,the vibration control tests of cable-damper system was carried out,including with and without damper,rigidity,installment position.The experiment results show that the design method is reliable and the cable damping is increased.The frequency has small influence to antivibration performa... |
