Effect of materials and designs of brake rotor discs on factor of safety and displacement assessed using auto desk fusion360

Abstract

Brake rotor is one of the top safety elements in many rotating machines and automobile. The temperature distribution in the rotor, the displacement of the rotor and factor of safety during braking are important parameters which will decide about the safety of vehicle and life of the brake rotor. It is very important to study the influence of materials and design on the factor of safety and displacement for better selection of materials and design of brake rotor discs. In this investigation, three designs of rotor namely a solid disc, a ventilated rotor disc with radial slots and a newly designed rotor consisting aero foil grooves and fins are used which are made of cast iron, titanium alloy and C/C-SiC dual matrices composite material. These discs are modeled in Autodesk Fusion 360. The mechanical behavior such as variation of factor of safety and displacement of the rotor discs are analyzed using Autodesk Fusion360. It is found that titanium alloy seems to provide better distribution of factor of safety in all the three designs of rotor discs. It also gives minimum displacement whereas cast iron rotor gives maximum displacement under the gradually applied static load.
