Self-resetting damper capable of realizing double-stage energy consumption
According to the self-resetting damper capable of achieving double-stage energy consumption, corresponding variable slopes are machined on clamping plates and a cover plate respectively, when the damper is pulled or pressed, the clamping plates horizontally slide outwards or inwards, the slopes drive the cover plate to move outwards, and therefore a disc spring set is pressed. The axial force of the high-strength bolt is increased along with compression of the disc spring, then the normal contact force between the inclined faces is increased, and a variable friction mechanism of the damper is achieved. In the deformation process of the damper, deformation is concentrated on the disc spring set, and other components are all in the elastic stage. Due to the mechanical behavior of linear elasticity of the disc spring set, residual deformation does not exist after the damper is unloaded, and the self-resetting performance is achieved. The double-order mechanical behavior of the damper is achieved through the variable-slope structure of the clamping plate and the cover plate. By adjusting the relative size of the inclination angles of the adjacent slopes, the strength-rigidity proportional relation of the damper in different working stages can be flexibly adjusted, so that the damper adapts to all levels of seismic levels, and the damper has high initial rigidity.
本发明公开了一种可实现双阶段耗能的自复位阻尼器，夹板和盖板上分别加工有对应的变斜面，当阻尼器受拉或受压时，夹板向外或向内水平滑动，斜面带动盖板外移，从而使碟簧组受压。高强螺栓轴力随碟簧的压缩而增大，进而增大斜面之间的法向接触力，实现阻尼器的变摩擦机制。阻尼器变形过程中，变形集中于碟簧组，其它构件均处于弹性阶段。由于碟簧组线弹性的力学行为，阻尼器卸载后不会存在残余变形，具有自复位性能。夹板和盖板的变斜面构造实现阻尼器的双阶力学行为。通过调整相邻斜面倾角的相对大小，可以灵活调整阻尼器在不同工作阶段的强度刚度比例关系，从而适应各级地震水准，使该阻尼器具有较高初始刚度。
