|Title:||PRESSURE INFLUENCE ON HEATING OF VENTILATING DISC BRAKES FOR PASSENGER CARS|
Ž. VASILJEVIĆ S.
|Abstract:||© 2020 Society of Thermal Engineers of Serbia. The braking system is one of the most important elements in vehicle systems from the aspect of vehicle safety, besides the steering system and the internal combustion engine. During the braking process, the disc and pads absorb a large amount of kinetic energy that converted to heat. Owing to this frictional heating, it is necessary to compute the temperature distribution that will be ap-peared during the braking process, which is the main goal of this research pa-per. There are many factors that can be influenced to the distribution of fric-tional heat generated. One of the significant factors is the applied pressure by the brake pad on the braking disc. The results proved that when increased the applied pressure then the frictional heat generated increased too. It was devel-oped a new finite element model based on observed data from real vehicle. It was used ANSYS/WORKBENCH 14.5 software to perform the numerical analy-sis, module Transient Structural. Parts that are the most disposed to the thermal stress are braking pads. Also, it was found time period from 0 to 0.1 second is the most critical period during the whole braking period, because in this period, temperature rises rapidly, the maximum temperature occurred at 1.338 sec-onds, and after that it falls.|
