dc.description.abstractUneven brake pad wear is a significant concern in the operation and maintenance of large truck braking systems, particularly in commercial vehicles like Volvo trucks. This study examines the primary origins, effects, and possible remedies to this issue, emphasizing materials science and design optimization. A mixture of theoretical investigations, finite element analysis (FEA), and three-dimensional simulation modeling was employed to assess the frictional interactions between brake pads and discs under diverse operating situations. The study commences with a comprehensive examination of the physical qualities and composition of the brake pads and discs, emphasizing attributes such as compressive strength, thermal conductivity, and wear resistance. Multi-circuit pneumatic systems working pattern as well as the principal work of pneumatic braking system starting from the relatively old models of trucks was analyzed. Furthermore, the effect of friction forces resulting in the change of internal energy was showed. The primary findings of the 3D modeling indicated that temperature variations on the contact surfaces substantially enhance wear in specific regions of the pads. This was validated by FEA experiments, which detected hot patches and stress concentrations under severe friction. Furthermore, the modeling demonstrated how braking dynamics, including uneven drive force and disc surface irregularities, intensify the wear pattern. This paper proposes solutions that involve altering pad shape for improved pressure distribution, employing modern materials with enhanced thermal resistance, and optimizing cooling methods. Suggestions for future endeavors encompass the incorporation of machine learning algorithms for predictive maintenance and the examination of novel self-regulating brake systems. This study's conclusions seek to augment the reliability of brake systems, increase safety, and diminish maintenance expenses for Volvo trucks and comparable heavy-duty vehicles, thereby contributing to the overarching advancement of sustainable and efficient transportation technology.
