Abstract
Disc brakes, which are essential safety components in automobiles, are profoundly affected by conditions at the pad-to-rotor interface. In this research, 3D modeling of the brake system was conducted using CATIA, supplying a comprehensive visual representation crucial for our analysis. The finite element analysis (FEA) was performed with ANSYS Workbench, allowing for an in-depth examination of wear mechanisms and their associated temperature history. To closely mirror real-world scenarios, tests were conducted using the Bruker UMT system equipped with a heating chamber, adhering to the SAE J2522 standard. Despite the robust methodologies employed, achieving the desired wear performance proved challenging. A significant inconsistency was observed between experimental and the simulation results. This disparity underscores potential inadequacies in the current simulation models and highlights the need for a more precise inclusion of material properties. This study recommends refining these models, addressing their inherent limitations, and optimizing testing parameters. A pivotal suggestion is incorporating enhanced material properties into the 3D models to improve accuracy. With these enhancements, the aim is to bridge the gap between simulated and real-world brake wear performances, thereby promoting more reliable braking systems.
