Design and Analysis of a gray cast iron light vehicles Disc Brake

Disc brake is a device for slowing or stopping the rotation of a wheel. A brake disc (or rotor), is usually made of cast iron or ceramic composites (as well as Kevlar, carbon and silica), is coupled to the wheel or axle. To stop the wheel, friction material in the form of brake pads (mounted on a so called brake caliper) is forced hydraulically, pneumatically, mechanically or electromagnetically against both sides of the disc. Friction causes the disc and the attached wheel to slow or stop. Brakes convert frictional energy into thermal energy, but if the brakes get red hot, they will strike and stop work because they cannot dissipate enough temperature. This situation of failure is known as brake fade. Disc brakes bare to large thermal stresses during regular braking and extraordinary thermal stresses during hard braking. The aim of this paper is to design a disc brake and perform a numerical coupled structural field stress analysis.
