Design and analysis of disk rotor brake under tribological behaviour of materials

Abstract

The Enormous progressions in the field of automobiles have led their car engines to have enriched brake power in vehicles. The braking system's efficiency should be at par with the engine to decelerate the car from a given speed within a less braking distance. The disc rotor and brake pads design and material while counting other impacting factors contribute to braking efficiency. The friction coefficient is abate by the brake disc's overheat and to circumvent this issue, and the rotor disc should be adequately ventilated to allow maximum heat dissipation from the disc to the surroundings. The overheating of the disc rotor causes the surface to harden, making the brake pads challenging to seize them. By subsuming drilled contours on the rotor disc, the enhanced surface area aids in the rapid heat transfer from the rotor disc to the environment moderating the heat generated at the pad-disc interface. Anew drafted brake rotor discs with drilled contour and ventilated discs are model using SOLIDWORKS. Static structural and thermal analysis performed with different disc materials using the finite element simulation software ANSYS. Based upon the temperature gradient, the heat dissipation obtained from the study, it is evident that the newly designed discs are significantly efficient, with longer brake spans and no abundant reduction in coefficient of friction of brake pads. A comparative study stated out for the various materials of the disc rotor.
