CBTC仿真系统中列车速度计算分析及研究

在CBTC仿真系统中,速度计算对仿真系统的功能验证起着至关重要的作用。分析了地铁列车的牵引和制动特性,根据列车自身参数以及具体线路数据,计算列车运行阻力,建立速度计算的单质点动力学模型。为了更加真实、精确地模拟列车的实际运行过程,分析了影响计算列车速度的各种因素,包括时延、列车发生空转和打滑等各种情况,并给出校正及补偿模型。

In the CBTC simulation system,speed calculation plays a vital role in the functional verification of simulation system.Based on studying metro＇s traction and brake characteristic,according to train parameters and the specific line data,build up a single-particle dynamic model in calculating speed.For more real,accurately simulate the actual running of trains;analyze the various factors that affect the calculation of train speed,including time delay,slip/slide and others.Considering the above factors,build up a mathematical model of calculating speed.
