Design and Fatigue Analysis of Pneumatic Train Braking System by Using Aluminum Silicon Carbide and Carbon Epoxy

Abstract

A moving train contains energy, known as kinetic energy, which needs to be removed from the train in order to cause it to stop. By applying a contact material to the rotating wheels or to discs attached to the axles.  The material creates friction and sudden apply load like force, pressure.  The wheels slow down and eventually the train stops.  The material used for braking is normally in the form of a block or pad. The vast majority of the world's trains are equipped with braking systems which use compressed air as the force to push blocks on two wheels or pads on to discs.  These systems are known as "air brakes" or "pneumatic brakes". The existing air brake system of Railway coach has the following drawbacks due to excessive brake force on the brake blocks - structural cracks on wheel tread, brake binding and reduced life of brake block. The aim of the project is to overcome the above said drawbacks by reducing the effective brake force on the brake blocks without affecting the existing designed requirements. The design using computer aided design software catia v5 software. The analysis is applying different materials steel alloys of wheels and brake pads are composite materials.  Dynamic and fatigue errors and performance analysis using ansys.
