Abstract
The CRISFIS project (supported by ADEME agency) consists in jointly studying the
squealing and cracking aspects of the high power disc brakes for TGV very high speed trains. This
paper deals with the progress concerning the cracking part. An experimental and modelling strategy
is adopted in order to better understand and predict brake disc cracking. Braking tests conducted on
an industrial scale-one test bench are presented. In a first step, the influence of the pad-type on the
thermal loading applied to the disc is studied by means of an infrared camera and thermocouples
embedded in the pads and in the disc. In a second step, the thermal maps extracted from
thermographic monitoring are used as input data for thermal-mechanical calculations. Finally, the
results of modelling and tests are compared to the damage observed on the brake discs.
