Finite Element Modeling and Simulation of Thermal Distribution on Full and Ventilated Electric Vehicle Disk Brake

摘要

This paper examines the phenomenon of heat distribution on the disk while braking. Heat distribution on the brake disk is caused by the change of the kinetic energy into the mechanical energy. The energy change occurs during the process of braking due to the friction between the surfaces of the disk with the caliper pad. Friction also results in the increase of temperature, This phenomenon is very important to be highlighted in order to learn the characteristic of heat distribution occurs on the disk with different disk types namely ventilation disk and full disk. In addition, this study is also aimed to find out the effect of vehicle load on disk temperature during braking process. The purpose of this research is to analyze the thermal distribution of a vehicle disk brake. The thermal distribution on the disk brake is investigated using ANSYS CFX. This simulation results provide useful information for identifying the influence of different models of disks brake as well as the vehicle load with regard to the distribution of heat that occurs during the process of braking.
