Thermo-mechanical performance of automotive disc brakes Daanvir Karan Dhir Abstract The kinetic energy of the vehicle is converted into mec

2、hanical energy while braking which leads to heat dissipation and temperature rise of the disc and the disc-pads. The aim of this investigation was to study the rise in temperature of an automotive disc brake at the time of braking and its effect on disc durability using finite element method. Applic

3、ation of a specified braking torque on the rotor led to generation of heat flux. The heat flux generated and the heat transfer coefficient taken into consideration were numerically analyzed, which were then used to calculate the rotor rigidity, maximum temperature rise on the disc rotor. The rotor w

4、as further loaded with thermo-mechanical cyclic stresses which were used to analyze the durability and fatigue factor of safety of disc. The influence of variations in disc rotor geometry i.e. holes and airfoil vents in comparison to a simple flange type disc were studied and their effect on maximum

5、 temperature rise and disc durability has been investigated by modeling and conducting FEM techniques in Solid works and ANSYS respectively. Keywords: Braking torque; disc brake; heat flux; thermo-mechanical analysis; thermal fatigue 1. Introduction A braking system is one of the most important safe

6、ty components of an automobile. It is mainly used to decelerate vehicles from an actual speed to a desired speed. Friction based braking systems are still the common device to convert kinetic energy into thermal energy, through friction between the brake pads and the rotor faces 3-7.Disc brakes operate with less fade as compared to drum brakes under the same conditions. An additional advantage of disc brakes is their linear relationship between braking torque and pad/rotor friction coeffici
