REVIEW OF MODELLING OF TEMPERATURE DISTRIBUTION IN SOLID BRAKE DISC

ABSTRACT

Automobile sector is an important industry that has a crucial role in balancing the world economy. One of the key research area that every researchers concentrate is on the safety of the passengers. Breaking is a crucial portion of automobile, it plays a significant role in safeguarding passengers. For effective braking system, thermal stability during the braking process is necessary. This thermal stability can be achieved only with the proper heat removal from the brake rotor disc and brake pads, where frictional effects are more. In the present proposed work, a novel semi-empirical model for brake design has been discussed and the temperature distributions in an isotropic and orthotropic type brake rotor are presented. This review will help the research fraternity to understand the thermal deformation, which is affected by material and braking mode.
