摘要:
高速磁浮交通车辆现行检修制度大多采用预防性计划维修模式。计划修模式下，高速磁浮交通车辆的检修能力利用率较低，这在一定程度上影响了列车运行的可靠性和线路的运力，导致配属列车数和车辆基地规模的增加，为此亟需进行检修制度的优化。简述了现行高速磁浮交通车辆检修制度，分析其存在的不足。对高速磁浮交通车辆运行特点及零部件技术特征进行了分析，明确了高速磁浮交通车辆与传统轮轨车辆间的本质区别，二者的车辆故障规律差异很显著。基于高速磁浮交通车辆的设备特征及故障特征，对其采用均衡修的适应性及可行性进行分析。高速磁浮交通车辆具备在线诊断系统，可随时收集车辆各部件的运转状态，能适应优化后更为精益的检修制度。高速磁浮交通车辆维修工作中应引入均衡修策略，根据零部件不同的故障规律及故障影响情况，建立以零部件为重点检修对象的均衡修制度。可参考成都地铁的车辆均衡修模式，将高速磁浮交通车辆双周检、三月检及定修的检修内容拆分到月检和专项修中，以此减小车辆的维修频次，压缩列车扣修时间，提高列车利用率。
Abstracts:
Current maintenance system of high-speed maglev transit vehicle mainly adopts preventive planned maintenance mode. Under this mode, the utilization rate of high-speed maglev transit vehicle maintenance capacity is low, which would affect train operation reliability and line capacity to some degree and also lead to the increase in the number of allocated trains and the scale of vehicle base, thus it is urgent to optimize the maintenance mode. The current high-speed maglev transit vehicle maintenance system is briefly described, and the shortcomings are analyzed. Through analyzing the operation characteristics and component technical characteristics of high-speed maglev transit vehicles, the essential difference between them and conventional wheel-rail vehicles is clarified, the difference in vehicle failure law between the two is also significant. Based on the equipment characteristics and failure characteristics of high\|speed maglev transit vehicles, the adaptability and feasibility of balanced maintenance are analyzed. High-speed mag-lev transit vehicle is equipped with an online diagnosis system, which can collect the operation status of all vehicle parts at any time and can adapt to the optimized leaner maintenance system. It is recommended to introduce balanced maintenance strategy into the maintenance work of high-speed maglev transit vehicle, and establish a balanced maintenance system focusing on parts and components according to their different failure law and failure impact. By referring to the balanced maintenance mode of Chengdu Metro, the maintenance contents of bi-weekly inspection, three-month inspection and scheduled maintenance are divided into monthly inspection and special maintenance, so that vehicle maintenance frequency and train maintenance time are reduced, and train utilization rate is improved.
