摘要：

In this research, two major models are used for calculation of frictional heat generation: namely macroscopic and microscopic model. In the macroscopic model, the law of conservation of energy or First Law of Thermodynamics is taken into account. And for the microscopic model, parameters such as the duration of braking, velocity of the vehicle, dimensions and geometry of the brake system, materials of the disk brake rotor and the pad are taken into account. For calculation of prescribed heat flux boundary condition in this model two kinds of pressure distribution is considered: uniform wear and uniform pressure. In high demand braking applications, vented disks consisting of two rubbing surfaces separated by straight radial vanes are normally employed as they utilize a greater surface area to dissipate heat. Within this paper the conduction heat transfer into a high performance passenger car front brake disk has been investigated using Finite Element Method. © 2008 Asian Network for Scientific Information.
