Annular installation sling tuned mass damper vibration reduction device
The invention provides a vibration reduction device of a ring-direction-mounted sling tuned mass damper, and belongs to the field of vibration control and energy dissipation and vibration reduction. The problems that an existing suspension bridge is not high in vibration reduction applicability, a damper cannot achieve the ideal effect, and installation is limited are solved. The damping device is connected with a main body structure through a stiffening plate connected through a bolt to conduct damping on the main body structure, mass blocks are connected with a lower bottom plate of an annular shell through vertical limiting springs and connected with an inner baffle of the annular shell through horizontal limiting springs, annular damping springs are connected between the adjacent mass blocks, and the annular damping springs are connected with the lower bottom plate of the annular shell. The annular damping spring provides damping force through stretching or compression to achieve dissipation of vibration energy. According to the annularly-arranged damping device, the shearing resistance of the sling is not affected, the torsion resistance of the sling is improved, the service life of the sling can be effectively prolonged, and the annularly-arranged damping device is simple in construction device, easy to manufacture and high in practical value.
本发明提出了一种环向安装的吊索调谐质量阻尼器减振装置，属于振动控制、消能减振领域。解决了现有悬索桥减振适用性不强，阻尼器达不到理想效果、安装受限制的问题。该减振装置通过螺栓连接的加劲板与主体结构连接，对主体结构减振，质量块通过竖向限位弹簧与环向外壳的下底板连接，通过水平限位弹簧与环向外壳的内挡板连接，相邻质量块间连接有环向阻尼弹簧，环向阻尼弹簧通过拉伸或压缩提供阻尼力实现振动能量的耗散。本发明所述的环向布置的减振装置，不影响吊索的抗剪性能且提高了吊索的抗扭性能，可有效提高吊索的使用寿命，构造装置简单，制作简单，具有很高的实用价值。
