摘　　要：钢轮钢轨式轨道交通车辆的动力最终来源是车轮和轨道之间的相互作用力——黏着力,列车的黏着力与其质量直接相关。地铁的客流特点决定了地铁列车整车的质量分布是相对均匀的,但是上海浦东机场线因其特殊的运营需求,可能出现不同车厢之间载荷极不均匀的工况,针对此特殊工况在既有的牵引力和电制动力分配策略的基础上,优化了列车牵引力和电制动力的分配方案,避免了因车辆载荷不均衡所导致的车轮空转和打滑的问题,并最大限度地减小了牵引力和电制动力的损失。Rolling stocks with steel wheel running on steel rails get the driving force from the interaction between wheel and rail,which is called adhesion.The adhesion is directly related to vehicle＇s weight.Passenger flow characteristics of the regular metro vehicle require that the vehicles＇ weight distribution shall be relatively uniform,but Pudong Airport Line in Shanghai displays extremely uneven loading conditions between different cars due to its special operation demands.Considering the special working condition,and base on the existing traction and electrical braking force distribution strategies,the distribution method of traction force and electric braking force is optimized,.This new method could avoid wheel idling and skidding that is considered as the main causes for load imbalance,and minimize the loss of traction and electrical braking force.
