Novel continuous supporting floating rail type vibration reduction fastener system
The invention discloses a novel continuous supporting floating rail type vibration reduction fastener system which comprises a rubber wedge buckled and pressed at a rail waist, a plurality of mass rods are arranged in the rubber wedge, and the mass rods are parallel to the main stress direction of the rubber wedge under transverse load and perpendicular to the main stress direction of the rubber wedge under vertical load. The mass rod is filled with particles. The fastener system is based on the technology combining the particle damping technology and the vulcanization mass rod, vibration of the steel rail can be reduced, the influence of noise on the environment along the rail can be reduced, the transverse rigidity can be increased, steel rail corrugation can be restrained, meanwhile, particle damping can play a role in energy absorption in a wide frequency band, and the service life of the steel rail is prolonged. The floating rail fastener is greatly improved on the basis of a traditional floating rail fastener.
本发明公开了一种新型连续支承浮轨式减振扣件系统，包括扣压在轨腰处的橡胶楔块，所述橡胶楔块内部设置有多个质量棒，所述质量棒平行于橡胶楔块横向载荷下的主应力方向，并垂直于橡胶楔块垂向载荷下的主应力方向，所述质量棒内部填充有颗粒。该扣件系统基于颗粒阻尼技术和硫化质量棒相结合的技术，不仅可以减小钢轨的振动，降低噪声对轨道沿线环境的影响，而且还能够增加横向刚度，抑制钢轨波磨的产生，同时颗粒阻尼可在较宽频段内发挥能量吸收的作用，在传统浮轨扣件上有了很大的提升。
