DESIGN AND ANALYSIS OF ROTOR DISC IN DISC BRAKE

SYSTEM

ABSTRACT

The disc brake is a device for slowing or stopping the rotation of a wheel. Repetitivebraking of the vehicle leads to heat generation during each braking event. Transient

Thermal and Structural Analysis of the Rotor Disc of Disk Brake is aimed at evaluatingthe performance of disc brake rotor of a car under severe braking conditions and thereby assist in disc rotor design and analysis. Disc brake model and analysis is doneusing ANS S workbench !".#. The main purpose of this study is to analysis thethermomechanical behavior of the dry contact of the brake disc during the brakingphase. The coupled thermal$structural analysis is used to determine the deformation

and the %on &ises stress established in the disc for the both solid and ventilated discwith two di'erent materials to enhance performance of the rotor disc. A comparisonbetween analytical and results obtained from ()& is done and all the values obtainedfrom the analysis are less than their allowable values. *ence best suitable design+material and rotor disc is suggested based on the performance+ strength and rigiditycriteria.
