| 摘 要： | 鉴于目前实桥上高阻尼橡胶圈是利用的高阻尼橡胶的挤压性能,而不是耗能更好的剪切性能,材料利用率低,本文通过高阻尼橡胶减振器试件剪切性能试验,获得了频率、应变幅值、厚度等各种参数对高阻尼橡胶减振器试件的影响规律,并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;最后讨论了减振器刚度、安装位置、橡胶材料、拉索长度等参数对减振效果的影响。

| Abstract: | In view of the high damping rubber rings use the press capability of high damping rubber on the solid bridge at present,the utilization ratio of materials is low.The high damping rubber stay cable damper is put forward.By way of shearing capability test of the high damping rubber damper specimens,the laws of effects concerning frequencies,strain range and layer's thickness on the behavior of damper speciments are obtained.With the shearing capability over the press one of high damping rubber in energy dissipation,one kind of simple and practicable design method of outer damper is presented.Last,the influence of several parameters like damper rigidity,installation,rubber materials,length of cable on the damping effects are discussed. |
