A Study on the Thermal Behaviour of Automotive Disc Brakes Using FEA and Dynamometer

FEA와 다이나모메터를 이용한 자동차 디스크 브레이크의 열적 거동에 관한 연구

While braking cars, a large amount of energy is taken into the brake system in a short period of time. This leads to some problems ; cracking of the disc, non-uniform wear of pad and disc, fade. Thus it is important to measure the contact thermal behaviour precisely between disc and pad. The measurements must be considered to design the brake system. The paper describes methods to analysis the problem of the thermal behavior on the ventilated disc with ANSYS-a program of FEA and a brake dynamometer. According to this way, the paper can present the error between the data by the dynamometer and the results of analysis by ANSYS.
