Damping force controllable viscous damper and intelligent monitoring and control system thereof

The utility model discloses a damping force controllable viscous damper and an intelligent monitoring and control system thereof. The damper comprises a cylinder body, a piston and a piston rod, wherein the inside of the cylinder body is separated into a main cylinder and an auxiliary cylinder; the main cylinder is filled with a damping medium consisting of polyethylene glycol and nano-scale silicon dioxide particles together; the silicon dioxide particles are suspended and dispersed in the polyethylene glycol; the piston is arranged inside the main cylinder and can move back and forth along the axial direction of the main cylinder so as to drive the piston rod connected with the piston to move together; and one end of the piston rod penetrates through a damping hole formed in the piston and the other end of the piston rod extends into the auxiliary cylinder. The utility model also discloses the corresponding intelligent monitoring and control system. By the damping force controllable viscous damper and the i
