摘要
以半挂汽车列车为研究对象,建立整车数学模型、轮胎模型、PID控制器模型、气压系统模型和滑移率的计算模型。对所建立的半挂汽车列车防抱死制动系统数学模型进行仿真研究,得出在干路面、湿路面和冰路面上的仿真曲线。仿真结果表明,建立的防抱死制动系统数学模型可靠,能达到较为理想的制动控制效果,验证了半挂汽车列车防抱死制动系统具有良好的制动性能和方向操纵性。
The paper establishes a semi-trailer model and simulation for ABS application including body model,tire model,PID controller model,barometric system model and slip ratio model.The mathematical model of ABS system is simulated,and simulation curves are obtained on dry,wet and ice pavements.The simulation results show that the mathematical model is reliable;its braking performance is good;and the anti-lock braking system has an excellent braking performance and direction maneuver ability.
