Particle damping steel rail dynamic vibration absorber and vibration reduction steel rail
The invention relates to the technical field of steel rail vibration reduction, in particular to a particle damping steel rail dynamic vibration absorber and a vibration reduction steel rail. The particle damping steel rail dynamic vibration absorber comprises a steel rail buffer layer, impact particles and a shell. The steel rail buffer layer is used for being laid on the side wall of a steel rail, the shell is used for covering the steel rail buffer layer to form a closed cavity, and the impact particles are contained in the closed cavity. The steel rail buffer layer is made of an elastic material. The vibration reduction steel rail comprises the particle damping steel rail dynamic vibration absorber. The problem that the vibration isolation and noise reduction capacity of an existing damping steel rail is limited is more effectively solved, and the vibration reduction and noise reduction frequency is further reduced.
本发明涉及钢轨减振技术领域，具体涉及一种颗粒阻尼钢轨动力吸振器及减振钢轨。颗粒阻尼钢轨动力吸振器包括钢轨缓冲层、冲击颗粒和外壳。钢轨缓冲层用于铺设于钢轨侧壁，外壳用于罩设于钢轨缓冲层以形成封闭腔室，冲击颗粒容纳于封闭腔室。钢轨缓冲层由弹性材料制成。减振钢轨包括上述颗粒阻尼钢轨动力吸振器。其更加有效地解决了现有阻尼钢轨隔振降噪能力有限的问题，并进一步地降低了减振降噪频率。
