Abstract
In this paper the temperature distributions over the region of a brake disc joining the rubbing path and the mounting flange are calculated. The two separate cases of braking, that of the transient temperature distribution produced by a single brake application and that of the steady-state conditions existing after a long period of steady braking downhill or repeated brake applications, are treated. A numerical method is employed for solution, involving setting up equations expressing the heat balance at every region in the disc, and solving these with the aid of a digital computer. Temperatures calculated by this method for a particular brake disc are compared with experimentally determined temperatures and show good correlation.
