摘要
本文设计了一种新型双楔块式汽车线控制动器。为了分析所设计制动器的制动性能,在MATLAB/Simulink中建立线控制动器的直流电机、电机摩擦、传动系统、制动力、轮胎、1/4车辆制动的数学模型,提出了用摩擦片刚度来预估制动力的方法,并仿真分析了线控制动系统在阶跃、三角波输入信号下的制动力响应和系统的制动效能。结果显示,所设计的线控制动器可以满足国标GB21670-2008的要求。
This paper presents a new type of double- wedge type automotive Brake-by-brake (BBW). With the aimof investigating the braking performance of the proposed brake, the mathematical models of the DC motor, friction, transmission, braking force, tire and 1/4 vehicle are established in MATLAB/ Simulink. A method of predicting the braking force with the friction plate stiffness is proposed. The braking force response of the BBW system under the step and triangular wave input signal is simulated. The braking performance of the system is simulated and estimated. The results show that the proposed BBW can meet the requirements of GB21670-2008.
