Displacement amplification type friction energy dissipation device
The invention discloses a displacement amplification type friction energy dissipation device which comprises an upper inner steel plate, a lower inner steel plate and at least one friction energy dissipation unit. The displacement amplification type friction energy dissipation device is a symmetrical body and is provided with a horizontal symmetry axis x and a vertical symmetry axis y. And the upper inner steel plate and the lower inner steel plate are symmetrically arranged up and down relative to a horizontal symmetry axis x and can be horizontally staggered under the action of external force. Each friction energy dissipation unit comprises two friction plates, a rotating component and a rotating limiting component. The two friction plates are symmetrically arranged on the two sides of the upper inner steel plate and the lower inner steel plate; the inner wall surface of the top of each friction plate is directly or indirectly in friction fit with the upper inner steel plate; and the inner wall surface of the bottom of each friction plate is directly or indirectly in friction fit with the lower inner steel plate. According to the displacement amplification type friction energy dissipater, the displacement amplification factor of the energy dissipater can be flexibly adjusted by changing the position relation between the pin shafts and the friction plates, and the bearing capacity of the energy dissipater can be adjusted by increasing or decreasing the number of the friction plates, namely, connecting the friction plates in parallel.
本发明公开了一种位移放大型摩擦消能器，包括上内钢板、下内钢板和至少一组摩擦消能单元。位移放大型摩擦消能器为对称体，具有水平对称轴x和竖向对称轴y。上内钢板和下内钢板关于水平对称轴x上下对称布设，且能在外力作用下发生水平错动。每组摩擦消能单元均包括两块摩擦板、转动部件和转动限位部件。两块摩擦板均对称布设在上内钢板和下内钢板的两侧；每块摩擦板的顶部内壁面均直接或间接与上内钢板摩擦配合；每块摩擦板的底部内壁面均直接或间接与下内钢板摩擦配合。本发明提供的一种位移放大型摩擦消能器，通过改变销轴和摩擦片的位置关系可灵活调整消能器的位移放大倍数，通过增减摩擦板数量，即摩擦板并联，可调整消能器承载力大小。
