Abstract：Depending on the FEM model of wheel load drop, the dynamic responses are simulated and calculated for different railway structures impacted by a falling wheel-set and the track’s vibration isolation performance compared among the common elastic rail fastener,the felting plate elastic rail fastener and the super-elastic fastener. Especially the dynamic responses are analysed with considering the influence of fastener components parameter (mass and stiffness). The results show that the vibration-reduction and vibration-isolation were improved by considering the parameter of fastener components and supply consultation for the elastic fasteners design.
