Problems solved by technology

The friction damper is also an excellent energy dissipation and vibration reduction device. The existing friction damper generally only provides a constant friction force, and cannot adjust the friction force according to the vibration size, so as to achieve better vibration reduction under different vibrations.

Abstract

The invention relates to a lead extrusion and friction composite damping device and a using method thereof. The lead extrusion and friction composite damping device comprises a rectangular box, wherein a moving plate with two ends respectively penetrating through a box body is horizontally arranged in the box body, a connecting hole connected with an external supporting member is arranged at the end, penetrating through the box body, of the moving plate, a longitudinal conical protrusion is arranged on the front side face, located in the box body, of the moving plate, at least two longitudinal arc-shaped protrusions are arranged on the rear side face, located in the rectangular box body, of the moving plate, a friction plate and a friction plate adjusting mechanism are arranged on the front side, located at the longitudinal conical protrusion, in the box body, a lead body is filled in the cavity where the longitudinal arc-shaped protrusions are located in the box body, and longitudinal bolts connected with a structural body are further arranged on the base plate of the box body. The lead extrusion and friction composite damping device is simple in structure, achieves better vibration reduction effect under the condition of different vibration, and the using method is simple.

Description

technical field [0001] The invention relates to a lead extrusion friction composite damping device and a using method thereof. Background technique [0002] The lead squeeze damper is an excellent energy-dissipating vibration-damping device, which is widely used in the vibration-damping control of structures. The extruding shaft of the existing lead extruding damper generally adopts a cylindrical shape, and the convex working range is limited, and the vibration damping effect needs to be improved. The friction damper is also an excellent energy dissipation and vibration reduction device. The existing friction damper generally only provides a constant friction force, and cannot adjust the friction force according to the vibration size, so as to achieve better vibration reduction under different vibrations. Effect. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a lead extrusion friction co...
