Investigation of the heat distribution in dry friction systems during fade and recovery using fiber-optic sensing and infrared technology

Abstract The design of dry-running friction pairings and systems determines not only their installation space costs, but also reliability under critical load conditions, for example in emergencies, the case faults, event misuse. While knowledge contact pattern is highly important development clutches brakes, contact-related measurement temperature these has yet been solved a satisfactory manner. Despite its importance, distribution measured few studies. Typically, measurements complete brakes are carried out using thermocouples only. In this study, new innovative test setup presented. This able to measure heat lining steel disk brake with high spatial resolution by means fiber optic sensing technology thermography. As novelty, it enables allows correlate fade recovery behavior. Contrary expectations, heterogeneous circumferential direction. Possible causes discussed simulation results. Along surface analysis, contributes investigation recovery.
