Embedded track dynamic vibration absorber
The invention discloses an embedded rail dynamic vibration absorber which comprises elastic units, mass units and damping units which are arranged on the two sides of the rail web of a steel rail, thetops of the elastic units are open, side faces of the elastic units make contact with the rail web and side wings at the bottom of the steel rail, and the elastic units are filled with the multiple mass units distributed discretely. The multiple mass units are solidified after being filled with liquid rubber, the upper surfaces of the solidified mass units are flush with the two side walls of theelastic units, point contact exists between the adjacent mass units, and the damping units are attached to the upper surfaces, solidified through the liquid rubber, of the elastic units and the sidefaces, not making contact with the steel rail, of the elastic units. According to the dynamic vibration absorber, the discrete mass units are solidified in the elastic units through the liquid rubber,the point contact between the steel balls is guaranteed, and meanwhile the frequency ratio and the mass ratio are guaranteed. The embedded rail dynamic vibration absorber is simple in structure, goodin vibration and noise reduction effect, stable in performance and wider in application frequency domain range, meanwhile, the steel rail corrugation is reduced, and the service life of the steel rail is prolonged.
本发明公开了一种嵌入式轨道动力吸振器，包括布置于钢轨的轨腰两侧的弹性单元、质量单元和阻尼单元，弹性单元顶部开口，一侧面与轨腰和钢轨的底部侧翼接触，内部填充有离散分布的多个质量单元，多个质量单元之间通过液态橡胶填充后固化，且固化后的上表面与弹性单元的两侧壁平齐，相邻的质量单元之间存在点接触，阻尼单元贴敷于弹性单元通过液态橡胶固化后的上表面，以及弹性单元与钢轨不接触的侧面。本发明所公开的动力吸振器采用离散的质量单元通过液态橡胶固化在弹性单元内部，保证了钢球之间的点接触，同时保证了频率比和质量比。本发明结构简单，减振降噪效果好，性能稳定，适用频域范围更广，同时降低钢轨波磨的产生，延长钢轨的使用寿命。
