Abaqus Validation: Coupled thermal-stress analysis of a disc-pad brake
Coupled thermal stress analysis: In this Abaqus tutorial, a 3D dimensional disk-pad heat transfer coupling simulation of the Red Flag CA7220 car has been done using the Abaqus software. The results of this simulation have been validated with a valid paper (Gao & Lin, 2002). For this analysis, the pressure from the brake pad to the disc is modeled and the heat generated by the friction between the pad and the brake disc is modeled. The final temperature distribution of the disc and brake pad is used to produce and operate the brake system.
Why 3D dimensional model?
Because using a two-dimensional model for thermal analysis implies that the contact conditions and frictional heat flux transfer are independent of theta. This may lead to false thermal elastic distortions and unrealistic contact conditions. The moving heat source may influence the fatigue stress and thermal cracking caused by the heat blow.
