Abstract
In order to study the longitudinal impact of multi-marshalling trains under the conditions of idling,traction and braking,this paper establishes a multi-degree-of-freedom train dynamics model composed of two locomotives and eight freight cars through the rail module of the multi-body dynamics software Simpack,and sets the boundary conditions of the simulation combined with the track irregularity encountered in the actual operation of the train and the forces in different operating conditions.Through the simulation results,the longitudinal impact of multi-marshalling trains under different working conditions is analyzed.The simulation results show that the longitudinal impact of the train is small and the relationship between the longitudinal impact force and the speed is not linear;the longitudinal impact force between trains under emergency braking is slightly larger than that under constant braking;during train traction and braking,the maximum longitudinal impact force appears in the buffer device connected to the locomotive and the truck.关键词
