초록
The present research aims to develop aluminum disc brakes to replace existing cast iron disc brakes in automobiles. The foundation for developing an aluminum disc is laid by investigating the performance characteristics of existing cast iron disc brakes and comparing those characteristics with those of aluminum disc brakes. This study involves FEM thermal/structural analysis of disc materials and experimental tests using a brake dynamometer. The results of this study show that, aluminum discs have not only better thermal/mechanical properties than existing cast iron discs, including better heat, wear, and crack resistance, but also that aluminum discs. Weigh less than existing cast iron discs, which results in improved maneuverability. Aluminum discs will become a more essential part of automobiles as electric cars become the major means of transportation.
