Summary

A theoretical model of a wheel-track system considering the wheel, track and rail vibration absorbers is developed. This is used to predict the vertical dynamic behavior of the track for a high-speed moving wheel load subject to the excitation of wheel/rail surface roughness. Using a comparison of the PSD of the rail vertical displacement at the force point with and without the rail vibration absorbers, it is found that the absorber is effective in mitigating the force point responses of the rail subject to high-speed moving wheel load. However, the rail vibration absorber also makes the track system become more sensitive to the moving wheel load. Also the present parameter investigation of the rail vibration absorber shows that selecting suitable stiffness, mass and a damping loss factor for the absorber, a better performance is achieved in both rail vibration reduction and rail noise reduction.
