Motion type side rail type mass damper
The invention provides a movable side rail type mass damper, and relates to structural vibration control and energy dissipation and shock absorption. The mass damper comprises two curved-surface rails and at least one set of fixing blocks arranged between the two curved-surface rails, the fixing blocks are fixed to the surface of a controlled structure, the sides, close to the fixing blocks, of the two curved-surface rails are fixedly connected through two rail connecting pieces, and the sides, away from the fixing blocks, of the curved-surface rails are each provided with two rail wheels; two telescopic rod assemblies are arranged on the fixed block, springs and rod end pulleys capable of rotating relative to the springs are installed at the tail ends of the two telescopic rod assemblies correspondingly, the peripheries of the two rod end pulleys make contact with the surfaces of the two curved surface rails correspondingly, and the two rod end pulleys move relative to the curved surface rails when the controlled structure vibrates. According to the mass damper, different nonlinear control forces can be generated by flexibly selecting the shape of the curved surface track, so that the device can resonate with wide frequencies, the vertical load attached to the structure is small, and the occupied space is small.
本发明提供了一种运动式侧边轨道型质量阻尼器，涉及结构振动控制、消能减震。该质量阻尼器包括：两个曲面轨道以及设置于二者间的至少一组固定块，固定块固定于受控结构表面，两个曲面轨道的靠近固定块一侧通过两根轨道连接件固定连接，曲面轨道的远离固定块一侧分别安装有两个轨道轮，固定块上设置有两组伸缩杆组件，两组伸缩杆组件的末端分别安装有弹簧和能够相对其转动的杆端滑轮，两个杆端滑轮的外周分别与两个曲面轨道表面相接触，并在受控结构振动时与曲面轨道发生相对运动。本发明质量阻尼器通过灵活选择曲面轨道形状，能够产生不同的非线性控制力，使装置能够与广泛的频率发生共振，且附加于结构的竖向载荷小，占用空间小。
