TEMPERATURE DISTRIBUTIONS AND THERMAL DISTORTIONS OF BRAKE DRUMS

This paper presents calculated results of transient temperature distributions and the resulting drum distortions when band contact occurs between the rubbing surfaces during operation of a brake. The finite element method is used to compute the thermal distortion in drums when incomplete contact arising from previous distortion, manufacturing tolerances or shoe misalignment occurs. The results are compared with those obtained when there is complete contact between lining and drum. Both single and repeated brake applications made at regular intervals with convective cooling are considered. /Author/TRRL/
