Assembly type staged viscoelasticity-friction composite shock absorber
The invention provides an assembly type staged viscoelasticity-friction composite shock absorber, and belongs to the technical field of shock absorbers, the assembly type staged viscoelasticity-friction composite shock absorber comprises a viscoelasticity shock absorption unit, a self-resetting friction shock absorption unit and a middle connecting plate, and the viscoelasticity shock absorption unit and the self-resetting friction shock absorption unit are arranged on the two sides of the middle connecting plate respectively; each of the viscoelastic damping unit and the self-resetting friction damping unit comprises two fixed plates and a movable plate, the fixed plates are connected to the middle connecting plate, and the movable plate is arranged between the two fixed plates; a plurality of viscoelastic material blocks are arranged between a fixed plate and a movable plate of the viscoelastic damping unit, and a plurality of friction plates are arranged between a fixed plate and a movable plate of the self-resetting friction damping unit; a plurality of SMA wires are further connected between a fixed plate and a movable plate of the self-resetting friction damping unit, and the SMA wires are used for limiting displacement of the movable plate in the length direction of the fixed plate. Ineffective abrasion of the self-resetting friction damping unit and damage of the viscoelastic damping unit can be avoided, and energy dissipation and damping are effectively achieved.
本发明提供一种装配式分阶段粘弹性‑摩擦复合减震器，属于减震器技术领域，包括粘弹性减震单元、自复位摩擦减震单元和中间连接板，所述粘弹性减震单元和自复位摩擦减震单元分别设置在中间连接板的两侧；粘弹性减震单元和自复位摩擦减震单元均包括两块固定板和一块活动板，固定板连接在中间连接板上，活动板设置在两块固定板之间；粘弹性减震单元的固定板和活动板之间设有若干粘弹性材料块，自复位摩擦减震单元的固定板和活动板之间设有若干摩擦片；自复位摩擦减震单元的固定板和活动板之间还连接有若干SMA丝，所述SMA丝用于限制活动板沿固定板的长度方向位移；本发明能避免自复位摩擦减震单元的无效磨损和粘弹性减震单元的损毁，有效耗能减震。
