A Thermo-elastic Annular Plate Model for the Modeling of Brake Systems

Abstract

The friction forces generated during braking between brake pads and discs produce high thermal gradients on the rubbing surfaces. These thermal gradients may cause braking problems such as brake fade, premature wear or hot spotting and the associated hot judder phe-nomenon in the frequency range below 100 Hz. Further consequences are comfort reductions, a defective braking process, inhomogeneous wear, cut-backs of the brake performance and even damage of brake components. The present paper proposes a modeling concept that is targeted on this field of application and in-troduces the new Modelica class ThermoelasticPlate, which is implemented in the DLR FlexibleBodies li-brary.
