Intelligent fluid viscous damper based on laminated piezoelectric actuator

The invention relates to an intelligent fluid viscous damper based on a laminated piezoelectric actuator. The intelligent fluid viscous damper comprises a cylinder barrel with a main cylinder and a secondary cylinder, a piston, a main guide rod and a secondary guide rod, wherein the piston, the main guide rod and the secondary guide rod are located in the cylinder barrel; the tail end of the main guide rod is fixedly connected with the first end surface, corresponding to the main cylinder, of the piston; the head end of the secondary guide rod is fixedly connected with the second end surface, corresponding to the secondary cylinder, of the piston; the cylinder barrel is filled with viscous fluid damping materials; and the piston is provided with a damping hole penetrating through the first end surface and the second end surface. The intelligent fluid viscous damper further comprises the laminated piezoelectric actuator installed on the secondary guide rod, a valve installed on the damping hole and a transmiss
