Energy dissipation and shock absorption device
The invention discloses an energy dissipation and shock absorption device, and relates to the technical field of bridge engineering shock absorption, the device comprises an upper top plate, a lower bottom plate, a displacement amplification assembly and a damping mechanism, the top plate is connected with a main beam, and the lower bottom plate is fixed with a bridge pier; the displacement amplification assembly is arranged between the upper top plate and the lower bottom plate, is connected with the upper top plate and is used for amplifying the swing of the upper top plate relative to the transverse bridge direction of the lower bottom plate; the damping mechanism is arranged on the lower bottom plate and connected with the other end of the displacement amplification assembly so as to provide damping force when the upper top plate swings in the transverse bridge direction relative to the lower bottom plate. The displacement amplifying part is arranged between the upper top plate and the lower bottom plate, so that small relative displacement of the upper top plate relative to the lower bottom plate can be transmitted to the damping mechanism, swing of the main beam in the transverse bridge direction is amplified through the displacement amplifying part, and the damping mechanism is conveniently used for providing damping force to dissipate energy and reduce swing of the bridge in the transverse bridge direction.
本发明公开了一种消能减震装置，涉及桥梁工程减震技术领域，该装置包括上顶板、下底板、位移放大组件和阻尼机构，顶板与主梁连接，下底板与桥墩固定；位移放大组件设在上述上顶板和上述下底板之间，且与上述上顶板连接，用于将上述上顶板相对于上述下底板横桥向的摆动放大；阻尼机构设在上述下底板上，并与上述位移放大组件的另一端连接，以当上述上顶板相对于上述下底板沿横桥向摆动时提供阻尼力。通过在上顶板和下底板之间设置位移放大件，从而可以将上顶板相对于下底板之间的较小相对位移传递给阻尼机构，利用位移放大件，将主梁横桥向的摆动放大，以便于利用阻尼机构提供阻尼力以消能减震，减少桥梁横桥向的摆动。
