Self-resetting friction energy dissipation damper
The invention provides a self-resetting friction energy dissipation damper, and belongs to the field of structural vibration reduction or anti-seismic devices. The first layer of the friction device is a friction plate, the second layer is two friction blocks, and the third layer is a friction plate; disc spring baffles B are fixed to the two sides of the outer sleeve, the two sides of the inner sleeve make contact with the disc spring baffles B, push pipes are arranged on the outer sides of the disc spring baffles B respectively, and anchoring plates are arranged on the outer sides of the push pipes. The guide rod penetrates through the disc spring and is anchored to the disc spring baffle B and the disc spring baffle A. One side of the screw rod is anchored to the disc spring baffle A, and the other side of the screw rod is anchored to the anchoring plate on the far side. According to the invention, restoring force is provided for the resetting device through friction force variation generated by the friction device under the action of external reciprocating load, so that compression deformation of the disc spring caused by pre-compression applied to the disc spring in the damper during installation can be reduced. Compared with an existing disc spring type self-resetting energy dissipation damper, the disc spring type self-resetting energy dissipation damper can give full play to the deformation capacity of the disc spring, and the design target that a building structure is oversized and does not fall down in an earthquake is achieved.
本发明提供了一种自复位摩擦耗能阻尼器，属于结构减振或抗震装置领域。本发明摩擦装置第一层为摩擦板，第二层为两个摩擦块，第三层为摩擦板；外套管的两侧固定有碟簧挡板B，内套管的两侧与碟簧挡板B接触，碟簧挡板B的外侧分别设置有推管，推管的外侧设置有锚固板；导向杆穿过碟簧并锚固在碟簧挡板B和碟簧挡板A上，螺杆的一侧锚固在碟簧挡板A处，另一侧锚固在远侧的锚固板上。本发明通过摩擦装置在外部往复荷载作用下产生的摩擦力变化量对复位装置提供恢复力，可减少安装时对阻尼器中碟簧施加预压力引起碟簧的压缩变形。相比于已有的碟簧式自复位耗能阻尼器，本发明可以充分发挥碟簧的变形能力，实现建筑结构超大震不倒的设计目标。
