When an urban rail vehicle moves, its receptor obtains the current from the contact rail (CR) through the sliding friction. Thus, the receptor could be subject to localized overheating, which causes increased wear and even damage. Based on the dynamic equilibrium equations of the heat transfer and dissipation between the receptor and the CR (referred to as the boot and rail, BAR), and the dynamic ...
