The friction experiments are conducted on a pin-on-disc friction material testing machine. The sliding velocity, pressure, temperature and friction coefficient are measured. The effects of brake temperature, brake pressure and braking speed on the friction coefficient are examined. Based on energy conservation theory, the model of friction coefficient is established using statistical methods. Then a semi-empirical model of friction coefficient is established by regression analysis methods. And the effects of the temperature, brake pressure, the relative sliding velocity and these cross-terms on the friction coefficient are also discussed.
