Segmented combined energy dissipation and shock absorption viscous damper

The invention provides a segmented combined energy dissipation and shock absorption viscous damper. The damper comprises two main cylinders, a connecting cylinder, an active piston, two passive pistons, two blocking devices, a sealing ring, a viscous damping material, two spring devices, a guide rod and two joints. The connecting cylinder is connected with the two main cylinders, and the two passive pistons are respectively located in the two main cylinders and move with the active piston. The principle of the damper is that the guide rod moves to drive the active piston fixedly connected withthe guide rod to move to extrude the viscous damping material in the main cylinders to push the passive pistons to move, damping holes in the passive pistons restrict the moving speed of the passivepistons to generate high damping force and achieve the shock absorption effect. 本发明提供了种分段组合式耗能减震粘滞阻尼器，包括两个主缸、个连接缸、个主动活塞、两个被动活塞、两个封堵装置、密封圈、粘滞阻尼材料、两个弹簧装置、导杆、两个接头，所述连接缸连接所述两个主缸，所述两个被动活塞分别位于两个主缸之中，随着所述主动活塞的运动而运动。本发明种分段组合式耗能减震粘滞阻尼器
