  • In order to investigate the wheel/rail dynamic performance of a heavy locomotive,the effect of longitudinal force of the coupler on locomotive-track coupled dynamics was taken into account.The dynamic performances under emergency braking on a tangent track and a curved track were computed numerically on the basis of the measured coupler force and irregularity.The research results show that all safety indices meet the limited values when a heavy locomotive runs on a tangent track at a braking speed of 80 km/h and on a curved track at a braking speed of 60 km/h.
