Viscous damper testing device

The invention discloses a viscous damper testing device which comprises a stand column, a cross beam, a middle beam and a base are fixed to one side of the stand column, two lifting oil cylinders are fixed to the cross beam, a locking oil cylinder is fixed to one side of the middle beam and fixed to the stand column, and a damping wall is fixed to the lower portion of the middle beam. A movable working table is fixed above the base, a force sensor and an actuator are fixed at one end of the movable working table and fixed on the stand column, and a damping wall is fixed above the movable working table. According to the horizontal dynamic single shear system, the double-outlet-rod double-acting servo actuator is adopted, the low-damping large-gap design technology is adopted for the actuator, the good dynamic performance is guaranteed, a multi-benefit controller imported from Germany is adopted for the horizontal dynamic controller, the control precision is high, and the response is fast.
