Self-resetting viscous damper with variable damping
The damping-variable self-resetting viscous damper comprises a resetting cylinder and a damping cylinder which are coaxially connected, and a movable connecting rod is arranged in the resetting cylinder in a penetrating mode; one end of the reset spring is connected with the movable connecting rod, and the other end of the reset spring is connected with one end, opposite to the damping cylinder, of the reset cylinder; the part, located in the damping cylinder, of the movable connecting rod is sleeved with a rotating disc, and a piston is sleeved outside the rotating disc and connected with the damping cylinder through a piston sliding rail arranged on the inner wall of the damping cylinder. Through holes are formed in the turntable and the piston; the damping cylinder is filled with a damping medium; good reset capacity is achieved through the reset spring, the problem that the damper is difficult to reset and replace in the earthquake and after the earthquake is solved, and the adverse effect of residual displacement on equipment is also avoided; due to the fact that the multiple sets of through holes with different inner diameters are formed in the rotary disc, the damping of the damper can be adjusted according to needs, and the applicability of the damper is improved.
本发明公开了一种阻尼可变的自复位粘滞阻尼器，包括同轴连接的复位筒和阻尼筒，复位筒内贯穿设置有移动连杆；复位筒内布置有复位弹簧，复位弹簧一端与移动连杆连接，另一端与复位筒背向阻尼筒的一端连接；移动连杆位于阻尼筒内的部分套接有转盘，转盘外套接有活塞，活塞通过设置在阻尼筒内壁的活塞滑轨与阻尼筒连接；转盘和活塞上均开设有通孔；阻尼筒中填充有阻尼介质；本发明在通过复位弹簧实现了良好的复位能力，避免了震中和震后阻尼器复位和更换难的问题，也避免了由于残余位移对设备的不利影响；由于转盘上的设置有多组不同内径的通孔，能够根据需要调整阻尼器阻尼的大小，提高阻尼器的适用性。
