The invention discloses a track wheel annular vibration and noise reduction damper which comprises a damper ring body and a damper opening sealer, and a plurality of mass damping allocation blocks matched with each other and matched with the vibration mode of a wheel are arranged in the circumferential direction of the damper ring body; and the damper ring body is in clearance fit with a damper mounting groove in a wheel. According to the annular vibration and noise reduction damper for the rail wheel, the mass distribution, the damping distribution and the rigidity distribution of the annular damper are adjusted by adjusting the mounting position, the mass and the rigidity of the mass and damping deploying block, so that the vibration mode of the annular damper is matched with the vibration mode of the wheel; the vibration response mode in the wheel running process can be gradually stabilized to be in the optimal state, so that wheel rail resonance and resonance of other bogie components are avoided, and the vibration amplitude peak value and noise radiation of the wheel and wheel pair structure vibration in the vehicle running process are reduced to the maximum extent.

    本发明公开了一种轨道车轮环型减振降噪阻尼器,包括一个阻尼器环体和一个阻尼器开口封闭器,所述阻尼器环体的周向设置有相互配合与所述车轮振动模态匹配的若干质量阻尼调配块;所述阻尼器环体与车轮上阻尼器安装槽之间为间隙配合。本发明轨道车轮环型减振降噪阻尼器通过调整质量阻尼调配块的安装位置、质量和刚度,以调整此环型阻尼器的质量分布、阻尼分布以及刚度分布,从而达到此环型阻尼器振动模态与车轮的振动模态相匹配;使在车轮运行过程中的振动响应模态,可以逐步稳定处于最佳状态,以避免轮轨共振及其它转向架部件共振,最大限度地降低在车辆行驶过程中车轮及轮对结构振动的振幅峰值和噪声辐射。
