Comparison of Different Methods for the Determination of the Friction Temperature of Disc Brakes 1999-01-0138

In the paper the dynamometer investigations on evaluating of friction temperature in disc brakes have been described. The goal of these investigations was to compare different methods (thermocouples, pyrometers and thermoscanner) regarding to their accuracy and suitability for specified test procedures. The problems of the evaluation and the changing of the disc surface emissivity and a way of its correction have also been discussed. Furthermore the possibilities of non-contact measuring methods for the evaluation of non-homogeneous temperature distribution over the disc surface under various braking conditions have been shown.
