The wheel-rail combined power spectrum densities are transformed into time domain samples by IFFT method, and add abnormal corrugation samples. The samples were taken as the inputting disturbances of a vehicle-track vertical coupling dynamics model, and the interaction force of wheel/rail is calculated by the models of vehicle with traditional bogie frame and articulated frame of vehicle/track coupling system. Dynamic responses of wheels on corrugation track can be calculated. The results show that wheels vibration intensity of vehicle with articulated bogie is lower.
