Design and Analysis of Two Disc Brake Systems used in Motorcycles

Disc brakes are one of the important components in automobiles. Most of the automobiles are employed with disc brakes since they provide good performance. Now a day the design of conventional disc brake system is common in all the moving vehicles. This conventional disc brake generates more stress and temperature in the contact areas. This influences the performance of the disc brake system, and it control the stresses and temperatures in the disc brakes and it is possible to improve the performance.The main objective of the present Project is to compare the mechanical performance of a conventional disc-brake system with a newly designed perimetral disc-break system using the finite element method. Finite element models of the disc-brakes are created using Pro-E and analysis is carried out by ANSYS. The disc-brakes are simulated under the three different loading conditions i.e., two static and one thermal analysis. The static analysis is performed and the maximum stresses are found at the mounting holes for perimetral disc-brake. The perimetral disc-break shown good performance under the static conditions, with stress approximately close to or lower than those of the conventional disc-brake. For the residual stress simulation, the maximum stress concentration is at the inner piercing holes and found that there is a danger of yielding or crack initiation under repeated residual stresses.
