FATIGUE AND STRUCTURAL ANALYSIS OF DISC BRAKE

These day technologies go beyond us. For automotive field, the technology of engine develops very fast. Although the engineer gives priority for safety measure, but most consumers still have inadequate knowledge in safety system. Instead of having air bags, good suspension systems, good handling and safe cornering, there is one most critical system in the vehicle which is brake systems. Braking is a process which converts a vehicle’s kinetic energy into mechanical energy which must be dissipated in the form of heat. During the braking phase, the frictional heat generated at the interface of the disc and pads can lead to high temperatures. The frictional heat generated on the rotor surface can influence excessive temperature rise which, in turn, leads to undesirable effects such as thermal elastic instability (TEI), premature wear, brake fluid vaporization (BFV) and thermally excited vibrations (TEV). In this project, we have conducted a study on solid, drilled and ventilated type disc brake rotor of normal passenger vehicle. The project is aimed at evaluating the performance of disc brake rotor under braking conditions and there by assist in disc rotor design and fatigue analysis.
