Seesaw type amplification type energy dissipation extending arm capable of preventing out-of-plane instability
The invention discloses a seesaw type amplification type energy dissipation extending arm capable of preventing out-of-plane instability. The extending arm comprises an extending arm truss, an outer frame column, a seesaw type amplification device, a viscous fluid damper, a viscoelastic damper and out-of-plane instability preventing connecting steel plates. The seesaw type amplification device is hinged to the outer frame column through a left hinge point, and the seesaw type amplification device is hinged to the extending arm truss through a right hinge point; the seesaw type amplification device is respectively hinged with one end of the viscous fluid damper through the upper hinge point and the lower hinge point, and the other end of the viscous fluid damper is hinged with the extending arm truss; and the out-of-plane instability preventing connecting steel plates are fixed to the upper end and the lower end of the outer frame column and fixedly connected with the viscoelastic damper, and the viscoelastic damper is fixedly connected with a pin shaft of the upper hinge point or the lower hinge point. The energy dissipation extending arm is high in feasibility, the key technical problem of an existing energy dissipation extending arm with an amplifying device is solved, and the energy dissipation and shock absorption effects and the capacity of coordinating deformation of an inner cylinder and an outer frame are superior to those of an existing technical scheme.
