다아나모 실험을 통한 Al-MMC 브레이크 드럼의 제동성능 평가

The Braking Performance Evaluation of Al-MMC Brake Drum Using the Dynamometer

This study was carried out to investigate the braking performances associated with the friction coefficients and temperature fluctuations. Friction coefficient stability and maximum temperature of brake drums, made of an Al-MMC and conventional cast iron, were tested by the inertial brake dynamometer during 15 braking operations. Also the temperature distribution was analyzed by the finite element analysis(FEA). In this experiment, both lower temperature rise near the drum surface and less variation of friction coefficient, compared to those of cast iron, were observed with Al-MMC drums during braking operations.
