Embedded plate type large-stroke lead damper
The invention discloses an embedded plate type large-stroke lead damper, and belongs to the field of damping control. The embedded plate type large-stroke lead damper comprises cover plates, middle plates, a slide plate and lead blocks. The middle plates are buckled on the two surfaces of the slide plate respectively. The upper cover plate and the lower cover plate are buckled on the two surfaces of the middle plates respectively. Grooves are formed in the two contact faces between each middle plate and the slide plate respectively, and the grooves of the upper contact faces and the lower contact faces are opposite and form two rectangular cavities. Grooves are formed in the two contact faces of each cover plate and the corresponding middle plate respectively, the length of the grooves, in the shearing direction, of the cover plates is larger than the length of the grooves, in the shearing direction, of the middle plates, the grooves of each upper surface and the corresponding lower surface are opposite and form a section-variable cavity. The lead blocks are embedded in the cavities. A plurality of dampers are connected in series in an embedded mode; meanwhile, damping materials are layered, the space occupied by the dampers is narrowed, and the stroke of the lead shearing damper is increased; meanwhile, the shearing area of the lead blocks is enlarged, the energy consumption capacity of the lead shearing damper is improved, and the situation that the damper outputs force evenly when the displacement is large is avoided.
