THERMAL ASPECTS OF RAILWAY BRAKING

Friction brakes must be designed and dimensioned so that they can dissipate the heat generated during braking and yet avoid excessive temperatures and stresses at the friction interface. In this paper the principles involved and the many factors that influence braking temperatures are considered. Analytical and numerical methods are described that enable temperature distributions in the brake to be determined for both transient and continued braking. The solutions obtained by considering a one-dimensional heat problem have been applied to single stops made from high vehicle speeds and to continued braking down a steep Alpine descent as severe applications of importance to railway brake engineers.
