摘要
主要介绍广州地铁 1号线车辆用牵引 /电制动系统的防空转 /防滑系统。阐述了该系统所用蠕滑率控制原理 ,提出了系统内部各参数的计算方法 ,对虚拟列车参考速度和加速度的形成与调整以及如何依靠实际可利用粘着系数μs来识别空转 /滑行的产生作了详细的分析和说明。最后指出 ,该系统具有良好的动态保护性能 。
Introduction focuses on the anti slip/slide device, applying creep ratio control theory, for traction/electric braking system used on vehicles of Guangzhou metro line No.1. Calculation method of system parameters is illustrated. Detailed analysis and explanation is made on the formation and adjustment of virtual train reference speed and acceleration, as well as on the identification of generation of slip/slide by actually available adhesion coefficient. The system features excellent dynamic protection and high reliability.
