COUPLED THERMOMECHANICAL ANALYSIS OF DISC BRAKE ROTOR
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 2
Abstract
The importance of vehicle safety is increasing with the rapid increase in the vehicle population and corresponding increase in the number of accidents. Vehicle braking system is considered as one of the most fundamental safety-critical systems in modern vehicles as its main purpose is to stop or decelerate the vehicle. Brakes are exposed to large thermal stresses during routine braking and extraordinary thermal stresses during hard braking. With the introduction of disc brakes the effectiveness of braking has improved to higher level. Brake disc can mechanically fail if the heat and the stress which is developed are not properly dissipated. In order to meet these requirements, we have designed a ventilated disc and it is compared with conventional solid disc for structural, modal and Couple field analysis (thermal + structural). 3D design of disc is created in Solid Works whereas analysis is done in ANSYS WORKBENCH by using thermal-structural coupled method. We have compared the result on the basis of dissipation of the heat and the compressive stress which was developed while breaking. Also we have studied the influence of changing the rotor stiffness on braking effect.
