Transient Thermal Analysis of AlSiCp Composite Disc Brake

Disc brakes are devices which will slow down or stop the heading vehicle. During the process of braking the brakes get heated up. Repeated braking will cause the excessive heating of the disc and braking action becomes less effective when the disc is over heated. So it is very much necessary that the heat generated is dissipated faster or the disc material gets less heated. In this paper we have considered a metal Matrix Composite AlSiCp which will satisfy these criteria. An analysis of composite and CI disc brakes over a repeated braking is done and the results are analyzed. The current paper deals with transient thermal analysis of composite disc brake. Transient analysis is generally made on systems where the forces acting are varied with respect to time. Model of the disc brake is done in Creo. Here temperature distribution in composite disc brake and CI disc brake under dynamic conditions are compared and analyzed using Ansys workbench 15.0. The composite material selected is AlSiCp, as it has good mechanical properties, wear resistance and high thermal conductivity. The project aims at reducing the heat generated during repeated braking with the use of an AlSiCp composite disc brake
