Abstract

The vehicle braking system is considered to be one of the most important safety-critical systems in modern vehicles as its main purpose is to stop or decelerate the vehicle. The use of a specified braking torque on the rotor resulted in heat flux generation. The brake system may fail mechanically if the heat and stress produced are not properly dissipated. This paper represents a new solid disc brake rotor design with curved vents, holes and slots on the surface and analyzes the stress and temperature distribution in the rotor while performing the braking phenomena. SolidWorks is used to construct a 3D disc design and analysis is performed in the ANSYS workbench. Steady state thermal condition and static structure condition has been used to determine the temperature coefficient acting on the disc and to validate ductility and strength, correspondingly. The findings were measured based on the heat dissipation and the compressive stress that was generated during the brake. It can be seen from the simulation of the structural and thermal distribution that the currently available solid disc brake is outperformed by the proposed new disc structure. This result therefore provides a better understanding of the thermal and structural characteristics of the disc brake rotor and allows the automotive industry to create an optimal and efficient disc brake rotor for the motorcycle.
