| Abstract: | Based on the studies of locomotive traction power, braking behavior of vehicles and the factors related, a theoretical calculating method to determine the maximum longitudinal forces acting on rails by train is put forward in this paper. The results calculated, which define the magnitude of the traction force and the braking force limit caused by train, are verified by rated locomotive traction power and urgent braking tests of trains. |
