车载ATP制动曲线仿真研究

Brake Curve Simulationof ATP

针对车载列车自动防护(Automatic train protection,ATP)的速度监督功能,在列车安全制动模型的基础上,提出一种列车速度控制算法,并以南京地铁二号线的部分参数为例,在比较不同坡度值、牵引加速度、制动初速的条件下,进行计算仿真,验证车载ATP的超速防护功能。

In accordance with speed supervision function of ATP, this paper puts forward a train speed control curve algorithm on the basis of train safety brake model and some parameters of Nanjing Metro Line Two. On the condition of different gradient, traction acceleration and the speed before braking, this paper veri- fies overspeed protection function by computer simulation.
