A NUMERICAL STUDY OF THE TEMPERATURE AND STRESS DISTRIBUTION IN THE BRAKING DISK
Abstract eng: Peak temperatures in the brake system have been identified numerically using calculation procedures. These calculation approaches were validated on the simple rotating disk involving the heat transfer by a convection, conduction and radiation. Furthermore the stress calculation was carried out in order to identify the stress peaks. Calculations have been performed on the real train path including braking, accelerating and waiting at the train stations. Generally, the temperature peaks have been identified immediately after several braking periods within a short time interval. These temperature maxima, however, drop quickly due to the heat conduction and simultaneously the higher stresses in the disk material have been observed.
