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 hot spotting and the associated hot judder phenomenon in the frequency range below 100 Hz.
Some consequences of these undesirable vibrations are comfort reductions; a defective braking process; inhomogeneous wear; cutbacks 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 introduces the new Modelica class ThermoelasticPlate; which is implemented in the DLR FlexibleBodies library.
