Study of braking dynamics of long and heavy trains on track downlines with a curve

Abstract

The longitudinal dynamics aspects of the heavy and long train during braking is analysed in this research work. The braking systems of long and heavy trains are considered. The highest forces exerted on the couplings during braking are examined. Using the software package „Universal Mechanism" the numerical simulation of the operation of the braking system of long and heavy trains is performed. The entire train length and the impact of using the type of train braking system on longitudinal forces value during braking processes are considered as well. The particularities of braking on track down-lines with a curve of the long heavy trains are defined. Finally, basic conclusions are given.
