Self-resetting variable stiffness viscous damper
The invention discloses a self-resetting variable-stiffness viscous damper, and relates to the technical field of bridge anti-seismic dampers.The variable-stiffness viscous damper comprises a cylinder body, a piston assembly and a supporting assembly, through holes are formed in the two ends of the cylinder body respectively, and the cylinder body is filled with a damping medium; the piston assembly is slidably sleeved with the cylinder body. The two ends of the piston assembly extend out of the cylinder body through the through holes respectively, and a reset spring is fixed between one end of the piston assembly and the outer wall of the cylinder body. The hinge seats are fixed to the outer side wall of the cylinder body, the number of the supporting rods corresponds to that of the hinge seats, one ends of the supporting rods are rotationally connected with the hinge seats, the other ends of the supporting rods are fixedly connected with the ends, extending out of the cylinder body, of the piston assemblies, and initial rigidity is provided for the damper through the supporting rods. The rigidity of the damper is variable through connection and disconnection between the supporting rod and the piston assembly, and the damper can be repaired after being broken so as to be repeatedly used.
本发明公开了一种自复位的变刚度粘滞阻尼器，涉及桥梁抗震阻尼器技术领域，其中，变刚度粘滞阻尼器包括：缸体、活塞组件和支撑组件，缸体的两端分别开设有通孔，缸体内部填充有阻尼介质；活塞组件滑动套设在缸体内部；活塞组件的两端分别通过通孔延伸出缸体，活塞组件的一端与缸体的外壁之间固定有复位弹簧；多个铰接座固定在缸体的外侧壁上，支撑杆的数量与铰接座对应，支撑杆的一端与铰接座转动连接，支撑杆的另一端与活塞组件延伸出缸体的一端固定连接，通过支撑杆为阻尼器提供初始刚度。本发明中通过支撑杆和活塞组件之间的连接和断开，实现阻尼器的刚度可变，而且在其断裂后可以修复，从而反复使用。
