The invention relates to a mass-adjustable integrated multi-dynamic vibration absorber for restraining rail vehicle shaking. The vibration absorber comprises a bearing frame fixedly connected with an edge beam at the bottom of a vehicle body and a mass-adjustable integrated vibration reduction structure transversely arranged in the bearing frame. The mass-adjustable integrated vibration reduction structure comprises two oppositely-arranged mounting shafts of which the one ends are fixed to the left inner side wall and the right inner side wall of the bearing frame, an adjustable inertia mass unit which is arranged between the left mounting shaft and the right mounting shaft, and a rubber springs which are arranged on the mounting shafts in a sleeving mode and provide rigidity and damping for transverse movement of the adjustable inertia mass unit. Compared with the prior art, the vibration absorber has the advantages that: the installation is convenient and flexible, the assembly is easy, the damping effect is stable, vehicle shaking is effectively restrained, and vehicle running stability and riding comfort are improved.
本发明涉及一种抑制轨道车辆晃车的质量可调集成式多重动力吸振器,包括与车体底部边梁固定连接的承载架以及横向设置在承载架内的质量可调集成式减振结构,所述的质量可调集成式减振结构均包括一端固定在承载架左右内侧壁上的两个相对设置的安装轴、设置在左右两个安装轴之间的可调惯性质量单元以及分别套设在安装轴上为可调惯性质量单元的横移运动提供刚度和阻尼的橡胶弹簧,与现有技术相比,本发明具有安装方便灵活,装配容易、减振效果稳定、有效抑制晃车提高车辆运行平稳性及乘坐舒适度等优点。
