Metal friction self-resetting damper with displacement zooming function
The invention provides a metal friction self-resetting damper with a displacement scaling function, belongs to the technical field of structural energy dissipation and vibration reduction control, and can solve the problems that when a traditional self-resetting damper generates large displacement in an earthquake, a prestressed steel strand is prone to brittle fracture, and self-resetting cannot be achieved. The damper comprises a supporting component, a wedge block set, soft steel, an outer plate and a load control module. Wherein the wedge block group comprises two horizontal wedge blocks and two vertical wedge blocks, the two horizontal wedge blocks are connected with the left end and the right end of the supporting component respectively, the two vertical wedge blocks are arranged at the upper end and the lower end of the supporting component respectively, and the contact surfaces of the vertical wedge blocks and the horizontal wedge blocks abut against each other; the soft steel is fixed on the outer side of the vertical wedge block; the outer plate sleeves the outer side of the wedge block group and is in sliding connection with the soft steel; the load control module penetrates through the outer plate to be connected with any horizontal wedge block, and a spiral spring is arranged between the horizontal wedge block and the load control module. The method can be applied to building structures such as bridges and houses.
本发明提出一种具有位移缩放功能的金属摩擦自复位阻尼器，属于结构消能减振控制技术领域，能解决传统自复位阻尼器当地震产生较大位移时，预应力钢绞线易发生脆性断裂，无法实现自复位的问题。该阻尼器包括：支撑部件、楔块组、软钢、外板及载荷控制模块；其中楔块组包括二水平楔块和二竖向楔块，二水平楔块分别与支撑部件左右端连接，二竖向楔块分设于支撑部件上下端，竖向楔块与水平楔块接触面之间相互抵接；软钢固定于竖向楔块外侧；外板套设于楔块组外侧并与软钢滑动连接；载荷控制模块穿过外板与任意一个水平楔块连接，且在水平楔块与载荷控制模块之间设置有螺旋弹簧。本发明能够应用于桥梁、房屋等建筑结构当中。
