An Optimization Method of Car Friction Material Formula

In order to quickly gain an optimal friction material formula, base on the uniform design an optimization experiment formula was designed. Friction coefficient and wear rate of the friction materials were measured according to GB5763-2008. Through the comprehensive evaluation, the stability parameters of friction coefficient, offset factor of friction coefficient and comprehensive wear rate were gained and taken into the uniform design experiment as three results. Three quadratic regression models were acquired through the SAS software and a program. The comprehens ive analysis model of friction and wear properties was composed of three models. An optimal formula was calculated by the MatLab software and a program. The results show that the optimized friction mater ial had good stability of friction coefficient which was closed to the specified friction coefficient and lower wear rate.
