Frequency-adjustable vertical tuned mass damper
The invention discloses a vertical tuned mass damper with adjustable frequency, which comprises a mounting frame and a mass block, a spiral spring, a damping device and a spring steel sheet are fixedly connected between the mounting frame and the mass block, the spiral spring and the damping device are vertically arranged, the spring steel sheet is horizontally arranged, and the damping device is fixedly connected with the mounting frame. And the spring steel sheet is detachably connected with the mounting frame and the mass block. The spring steel sheet is of a sheet-shaped structure made of spring steel, and when the spring steel sheet is horizontally arranged, the spring steel sheet has the elastic deformation capacity in the vertical direction. The frequency is tuned and controlled by adjusting the number and the size of the spring steel sheets, and compared with direct adjustment and replacement of spiral springs, the replacement operation is simpler, and the adjustment precision is better; the horizontally-arranged spring steel sheets can limit the mass block to vibrate in the vertical direction as much as possible, the guiding effect is achieved, the influence of friction force generated by the guiding device on the device is avoided, and the starting sensitivity of the tuned mass damper is improved.
本发明公开了一种频率可调的竖向调谐质量阻尼器，包括安装框架和质量块，在所述安装框架和所述质量块之间固定连接有螺旋弹簧、阻尼装置、弹簧钢片，所述螺旋弹簧与所述阻尼装置竖直布置，所述弹簧钢片水平布置，且所述弹簧钢片与所述安装框架、所述质量块可拆卸式连接。所述弹簧钢片为由弹簧钢制成的片状结构，当弹簧钢片水平布置时，其在竖向具有弹性变形能力。本发明通过调整弹簧钢片的数量以及尺寸以调谐控制频率，相较于直接调整、更换螺旋弹簧，更换操作更加简单，调节精度更好；水平布置的弹簧钢片能够限制质量块尽量沿竖向振动，起到导向作用，又避免了导向装置产生的摩擦力对装置带来的影响，提高调谐质量减振器的启动灵敏度。
