Damping-adjustable stay cable viscous shear damper
The damping-adjustable stay cable viscous shear damper comprises a pile casing main body, an auxiliary mounting and positioning mechanism is arranged at the bottom of the pile casing main body, a stay cable is connected to the top of the pile casing main body through a bolt, and the surface of the stay cable is fixedly sleeved with a first cable clamp and a second cable clamp in sequence from bottom to top; a damper connecting mechanism is arranged on the left side of the bottom of the stay cable. Through cooperative use of the first cable clamp, the stay cable, the second cable clamp, the first connecting rod, the second connecting rod and the connecting shaft pin, double-cable-clamp double-point connection can be adopted, the distance between the double cable clamps is reasonably set, the positions of the cable clamps are adjusted, and it is ensured that at least one mounting point keeps away from a zero displacement point of a high-order vibration mode; the stay cable can transmit enough displacement and speed to the external damper, so that effective vibration of the damper is excited, and it is ensured that the damper can provide enough additional damping to the stay cable to restrain high-order vibration.
本发明公开了一种阻尼可调型斜拉索黏性剪切阻尼器，包括护筒主体，所述护筒主体的底部设置有辅助安装定位机构，所述护筒主体的顶部通过螺栓连接有斜拉索，所述斜拉索的表面从下到上依次固定套设有第一索夹和第二索夹，所述斜拉索底部的左侧设置有阻尼器连接机构。本发明通过设置第一索夹、斜拉索、第二索夹、第一连杆、第二连杆和连接轴销的配合使用，能够通过采用双索夹双点连接，通过合理设置双索夹之间的距离、调整索夹位置确保至少一个安装点避开高阶振型的零位移点，使得拉索能够传递足够的位移和速度给外置阻尼器，进而激励起阻尼器的有效振动，确保阻尼器能提供足够的附加阻尼给斜拉索来抑制高阶振动。
