The vibration and noise are the main hazards of rail transit. In order to achieve the purpose of reducing vibration and noise, we employ the constrained damping method on the wheel and rail; use finite element software to set a finite element model of standard wheel rail and damped wheel rail; then give them harmonic response analysis. The results showed that: the main resonance frequency of the standard wheels is at 2000 ∼ 4000 Hz; the main resonance frequency of the standard rail of is at 800 ∼ 4500 Hz; the reducing vibration effects of the damped wheel-rail are mainly at the centralized area of the resonant frequency response. Compared with the standard wheel and rail, the vibration response peak value of damped wheel-rail has significantly weakened. Under the wheel-rail loading, maximum axial and radial vibration response value of damped wheel-rail is around 30-35% of the standard wheel-rail, with vibration reduction rate up to 65-70%.
