Stress analysis and contact pressure distribution in different disc brake rotors

Continuous change and improvement in structure of disc brake rotor is important in design of braking system. Major focus is given on thermal and structural behavior of disc brake rotor for improved braking systems. In this article we propose a new structure by providing curved vents, holes and slots on the surface of solid disc brake rotor and analyze its stress distribution in rotor and contact pressure distribution in pressure pads. Ansys software package was used to model and analyze the disc rotors and pressure pads. Von Mises stress distribution and pressure distribution for new disc and the older solid disc brake rotor is compared. Transient behavior of these two factors from the start of braking to complete stop of vehicle is investigated. From the simulation of stress distribution and contact pressure variation it is seen that the traditional solid disc brake is outperformed by the new proposed structure of the disc. Stress distribution has significantly reduced whereas there is slight increase in contact pressure due to reduced surface area of new disc.Continuous change and improvement in structure of disc brake rotor is important in design of braking system.
