Abstract

EN It is impossible to directly observe wheel-rail interface during real operation of a rail vehicle and measure its instantaneous wear index. The idea to tackle the problem is to utilize thermography, which allows to read temperature values in the wheel-rail contact. The temperature increase stands for a change of internal energy of the wheel material, which in this case is supplied by frictional heat, which in turn can be associated with frictional wear of wheel-rail pair. On this basis, a novel method was formulated to measure the instantaneous wear of wheel and rail using non-contact thermography measurements.
