Low-prestress self-resetting asymmetric friction damping shock absorption device
The low-prestress self-resetting asymmetric friction damping device comprises an outer cylinder, an asymmetric damping unit and a self-resetting unit, one end of the outer cylinder is sealed, the other end of the outer cylinder is provided with an opening, the asymmetric damping unit is connected with the self-resetting unit in series, and the self-resetting unit is connected with the asymmetric damping unit in series. The asymmetric damping unit and the self-resetting unit are both movably fixed in the outer cylinder, the asymmetric damping unit is located at the sealed end of the outer cylinder, and the self-resetting unit is located at the open end of the outer cylinder; when the device is pulled, the asymmetric damping unit generates frictional damping, and the self-resetting unit generates elastic restoring force; when the device is pressed, the asymmetric damping unit does not generate frictional damping, and the self-resetting unit does not generate elastic restoring force. Compared with the prior art, the damper has the advantages of tension and compression asymmetric damping performance, low prestress, self-resetting and the like.
本发明涉及一种低预应力自复位非对称摩擦阻尼减震装置，包括外筒、非对称阻尼单元和自复位单元，所述外筒的一端密封，另一端设有开口，所述非对称阻尼单元串联自复位单元，所述非对称阻尼单元和自复位单元均可移动固定在外筒的内部，所述非对称阻尼单元位于外筒的密封端，所述自复位单元位于外筒的开口端；所述装置受到拉力时，所述非对称阻尼单元产生摩擦阻尼，且所述自复位单元产生弹性恢复力；所述装置受到压力时，所述非对称阻尼单元不产生摩擦阻尼，且所述自复位单元不产生弹性恢复力。与现有技术相比，本发明具有拉压非对称阻尼性能、低预应力、自复位等优点。
