Abstract

Abstract: The braking condition has great influence on the thermal-mechanical coupling characteristics of disc brake. A three-degree-of-freedom dynamic model of braking vehicle was built. The braking force was determined by an anti-lock braking system (ABS) which adopted the threshold-logical control strategy of wheel slip rate. With the model, anti-lock braking processes on dry and wet were simulated. In the meantime, for the sake of comparison, non-anti-lock braking processes were simulated on corresponding road. A thermal-mechanical coupling finite element model of a ventilated disc brake was established. Thermal-mechanical coupling characteristics of brake disc and brake lining were calculated under different braking conditions, and the characteristics under anti-lock braking condition were analyzed. The effects of ABS on the characteristics of the brake were studied through comparison with non-anti-lock braking condition. Through analysis, it is found that the variation of braking pressure and the difference in braking frictional thermal power due to ABS control will significantly affect the brake's thermal-mechanical coupling characteristics.
