澳大利亚重载列车纵向动力的研究

在进行BHP铁矿石重载运输时,列车平均轴重在35t以上、整列车由220辆车组成的情况已为数不少,列车的纵向动力常常会大于1000kN。20世纪90年代中期,高的列车纵向力导致列车沿着坡度大的坡道下行和在起伏很大的路段上运行时出现列车分离。与修改车辆维修工艺和操作程序一样,对列车驾驶方法进行了研究和修正,并对列车实际操作进行了调整。通过一系列的措施,大大减少了列车延误次数。

Research on Longitudinal Train Dynamics in Australia

In the heavy haul environment at BHP Iron Ore, where average axle loads are above 35 tonnes and trains longer than 220 cars are not uncommon, longitudinal train dynamics frequently result in forces greater than 1 000 kN. During the mid 1990s high longitudinal train forces were causing many train partings in track sections with steep downhill and undulating grades. Driving procedures were examined and modifications to driving strategies suggested which, in conjunction with modified maintenance and operational procedures, have been instrumental in dramatically reducing train delays.
