Abstract
When braking a freight train using brake pads, kinetic energy is converted by friction into thermal energy, part of which goes into the brake pads, the other part goes into the wheels, and from the wheels the heat goes into the rails and the environment. The purpose of the work is to determine the proportion of heat in the wheels of freight cars under different braking modes and different train speeds, as well as different loading of cars. In the work, the wheelset braking process was simulated using the finite element method in the SolidWorks environment. The calculations made it possible to establish the proportion of heat flows directed into the brake pad and into the rail under different braking modes of the freight train. The influence of ambient temperature and car loading on these fractions has been established. The results obtained make it possible to more accurately predict the temperature of the rolling surface and the side surface of the wheel rim, which will allow diagnosing the braking system of a freight train in motion.
