Abstract EN
Laying shock absorber fasteners is one of the effective countermeasures used to reduce the ground vibration induced from urban rail transit.
However, this kind of fasteners could cause severe rail corrugation.
Based on the “wheel-rail dynamic flexibility difference” mechanism, the optimization and further research of fastener stiffness were performed.
With the finite element method, the simple beam and board model of the rail system is established to study the vertical and lateral dynamic flexibility characteristics of rails below 1,200 Hz.
Within 5–40 kN/mm, a comparison is made between wheel-rail dynamic flexibility differences corresponding to the vertical stiffness and lateral stiffness of different fasteners.
The results show that 20 kN/mm and 10 kN/mm are the least and most suitable vertical stiffness values of fasteners, respectively; 40 kN/mm and 5–10 kN/mm are, respectively, the least and most suitable lateral stiffness values of fasteners.
The research and analysis results can be adopted as references for deciding the fastener stiffness of urban track.
