Modeling Ventilation System for Minimizing Temperature Amount of the Heat on the Contact Surface of the Brake Disc

When driving a vehicle, reliable braking system ensures maximum human safety. Increasing vehicle speed under driving conditions generate heat due to the friction between rotating disc and pads. Elevated temperatures accelerate brake disc contact surface thermal deformation and shortens the service life. The particles formed as a result of high temperature and friction coefficient on the contact surface of the brake disc must not be emitted into the atmosphere. The ventilation system ensures that particles do not escape into the atmosphere by installing a car air filter system in the outdoor air flow duct. Minimizing the amount of heat and temperature on the contact surface of the brake disc in the ventilation system leads to an increase in the service life of the brake disc. The present research is essentially dealing with the modeling and analysis of solid and ventilated disc brake using ventilation system test rig. Methods for design and analysis of optimal airflow rate ventilation system and modeling airflow control are established for analysis. The mathematical model of the fundamental parameters of the brake disc and ventilation system are established and the heat generation, heat flux, heat transfer, the behavior of airflow, pressure losses, air density, airflow rates, inlet and outlet speed on the ventilation system with the brake disc are carried using flow meters. The results were validated using the experimental data from ventilation system setup, which shows distribution of heat flow rate at the disc contact surface and temperature minimization. In the experiment performed, an average brake disc temperature reduction of more than 15% was observed.
