Abstract
In order to analyze the feasibility of running 5000t heavy-haul trains on a railway in a mountainous area, a longitudinal dynamic model of heavy-haul trains is established, taking full account of the actual horizontal profile of the railway line in the mountainous area. The results of the model are compared and analyzed with those of China Academy of Railway Sciences through a numerical example, and the results are in good agreement, which verifies the accuracy of the model. Based on this model, the longitudinal dynamic performance of planned running marshalling under the conditions of ramp traction, restricted ramp braking, emergency braking and resistance speed control braking is analyzed. The results show that the longitudinal impulse of the marshalling under each condition has a large margin compared with the safety standard. The study demonstrates the feasibility of 5000t heavy-haul train operation in the mountainous area from the perspective of simulation, and provides a theoretical basis for the safe operation of 5000t railway in the mountainous area.
