Side edge curved surface rail type mass damper
The invention provides a side edge curved surface rail type mass damper, and belongs to the technical field of structural vibration control and energy dissipation and shock absorption. The mass damper comprises a guide rail and two curved-surface rails symmetrical about the axis of the guide rail, the guide rail and the curved-surface rails are fixed to the controlled structure, the axis of the guide rail is the same as the vibration direction of the controlled structure, a sliding block capable of sliding relative to the guide rail is installed on the guide rail, and a balancing weight is fixed to the surface of the sliding block. A sliding groove perpendicular to the axis of the guide rail is formed in the surface of the balancing weight, two telescopic rod assemblies are arranged in the sliding groove, 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, and the peripheries of the two rod end pulleys make contact with the surfaces of the two curved surface rails correspondingly. And when the controlled structure vibrates, the control mechanism moves along the curved surface track. 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, and the occupied space is small.
本发明提供了一种侧边曲面轨道型质量阻尼器，属于结构振动控制、消能减震技术领域。上述质量阻尼器包括：导轨以及关于其轴线对称的两个曲面轨道，导轨和曲面轨道均固定于受控结构上，且导轨的轴线与受控结构的振动方向相同，导轨上安装有能相对其滑动的滑块，滑块表面固定有配重块，配重块表面开设有与导轨的轴线相垂直的滑槽，滑槽内设置有两组伸缩杆组件，两组伸缩杆组件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沿曲面轨道运动。该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，且占用空间小。
