Abstract: In the present research work, an attempt is made to study and analyse the behaviour of a disc brake assembly for fatigue and dynamic loads under finite life condition. Friction material cross section is varied in this work (no slot, single slot, double slot, three slot and multi slot) sliding against a gray cast iron disc. The pressure acting on the friction material is varied from 1 MPa to 4 MPa with sinusoidal loading for fatigue analysis. Dynamic analysis is performed by applying angular velocity to the disc and impact velocity to the friction material. Dynamic analysis is performed starting from 1,000 cycles to 100,000 cycles on the disc brake assembly. Both fatigue and dynamic analysis are performed based on few assumptions. The values of vonmises stress and deformation for different configurations of disc brake pad systems are evaluated using ANSYS software, finite element methods and the best configurations of materials are selected for the design.
