采用现场试验斜拉索-磁流变阻尼器减震系统进行了研究。结果表明磁流变阻尼器的安装,对斜拉索的振动具有显著抑制的效果,使斜拉索的平均阻尼比提高1.9至17.2倍,衰减时间缩短到1/3.6至1/12.6。调节阻尼器的控制电压可以获得拉索的最佳平均阻尼比和最短衰减时间。
The field test cable-magnetorheological damper damping system was studied. The results show that the installation of magnetorheological damper can significantly reduce the vibration of stay cables, increase the average damping ratio of stay cables by 1.9 to 17.2 times and reduce the decay time to 1 / 3.6 to 1 / 12.6. Adjusting the damper’s control voltage results in the best average damping ratio of the cable and the shortest decay time.
