Experimental & Analytical Investigation for Optimization of Disc Brake Heat Dissipation Using CFD

One of a vehicle's most crucial duties is braking. It is critical to design the braking system so that the automobile is still safe when braking. When the brakes are applied, the disc brakes dissipate a heat. The heat dissipation of the brake determines the braking system safety. The present investigation has been intended to estimate the heat dissipation rate of the disc brake; for different proposed disc brake structures using CFD and thermal analysis. The thermal stress has been computed at different load, speed and temperature. The outcome provides essential knowledge of the behavior of the disc airflow, which is critical for comprehending the entire airflow. Both local and global correlations could be established using different visualization techniques. It enables to understand the disc brake thermal stability. The temperature at the interface between pad and disc varies from 36.45°C to 97.8°C as the speed varies from 300 rpm to 1100 rpm and load from 20 N to 80 N. The steady state thermal analysis of a disc rotor was performed in order to evaluate the braking performance of a disc brake under braking conditions. Modelling software has been used to design the brake rotor, and CFD is used to analyse it. It can be reported that numerical, CFD & experimental analysis carried out on the proposed new disc brake design demonstrated optimized heat dissipation.
