Tuned damper
The invention relates to a tuned damper, which belongs to the field of shock absorption equipment of constructional engineering and comprises a base, a first substructure used for controlling vertical vibration of a suspension bridge and a second substructure used for controlling horizontal vibration of the suspension bridge in a combined manner, the bottom of the first substructure is hinged to the base, and the bottom of the second substructure is hinged to the base. The two ends of the base are further symmetrically hinged to the first substructures through the second substructures correspondingly, the base can transmit horizontal vibration and vertical vibration to the second substructures and the first substructures, and each first substructure comprises a support and a mass assembly used for storing inertial energy. The support and the mass assembly are fixedly connected through an elastic element a and a damper a which are used for generating natural vibration frequency. Natural vibration frequency is excited in a double-substructure nesting mode, vibration in the horizontal direction and vibration in the vertical direction can be acted at the same time, vibration and deflection of the bridge body in the horizontal direction are weakened, meanwhile, the first substructure is combined to control large vibration in the vertical direction, and vibration on the bridge body is subjected to balance control.
本发明涉及一种调谐阻尼器，属于建筑工程减震设备领域，包括基座、以及用于控制悬索桥竖直振动的第一子结构和用于组合控制悬索桥水平振动的第二子结构，所述第一子结构的底部铰接于基座，基座两端还分别通过第二子结构对称铰接于第一子结构，所述基座可传递水平振动和竖直振动于第二子结构和第一子结构，第一子结构包括支架、以及用于存贮惯性能量的质量组件，支架、质量组件之间通过用于产生自振频率的弹性元件a、阻尼器a固定连接；本发明采用双子结构嵌套方式激励自振频率，可同时作用水平方向和竖直方向的振动，减弱桥身桥身的水平方向上的振动和偏摆，同时组合第一子结构控制竖直方向上较大的振动，使桥身上的振动得到平衡控制。
