  • In order to decrease wheel-rail noise, wheel-rail noise predicting model and STTIN software were put forward, the structure parameter influence of slab track on wheel-rail noise was analyzed.It is pointed that wheel-rail noise rises while the stiffness of rail pad is higher than 200 MN·m-1, and the damping of rail pad drifts off the value of 100 kN·s·m-1, wheel-rail noise is almost indeclinable when modifying the stiffness of slab pad, but it decreases when increasing the mass of slab.The result shows that the stiffness and damping of rail pad are the key factors influencing wheel-rail noise, the mass of slab is the secondary factor, and the stiffness of slab pad primarily has no influence on wheel-rail noise.
