摘    要:针对强风沙运用环境与长交路运行工况对动车组关键系统及部件故障的影响特性,建立基于系统可用度的预防性维修周期决策模型;考虑兰新(甘肃兰州—新疆乌鲁木齐)高铁开行时间短、检修经验不足等问题,提出基于Monte-Carlo思想的统计模拟算法。利用兰新客运专线强风沙运用环境下的塞拉门服役故障信息,对决策模型分布函数进行定义、参数估计和假设检验;利用建立的模型在MATLAB环境下仿真计算塞拉门预防性维修周期,结合现场实验验证维修决策模型和算法的有效性。研究结果表明:塞拉门故障服从形状参数为0.779、尺度参数为315 158.178的双参数威布尔分布;随预防性维修周期增加,塞拉门的可用度先增加后减小,考虑到预防性维修的人员组织、均衡作业和修程间隔等因素,确定其维修保养运行里程为10万km。

Abstract: To investigate the blown sand environment influence on train-set fault occurrence under long routing operation, a preventive maintenance period decision model based on system availability was proposed. With inadequate running time and maintenance experience on Lanzhou—Xinjiang high-speed railway line, Monte-Carlo-based algorithm was presented for statistical simulation. Real service fault occurrence information of sliding plug door was employed for distribution function definition, parameter estimation and hypothesis testing. Finally, preventive maintenance period of sliding plug door was calculated with MATLAB programming using the suggested model, which was then validated by field test. The results indicate that the fault occurrence of sliding plug door submits to two-parameter Weibull distribution, where the shape parameter is 0.779 and scale parameter is 315 158.178. With the increase of preventive maintenance period, the availability of sliding plug door increases at first and then decreases. Taking factors such as personnel organization of preventive maintenance, balanced operation and repair interval into account, the maintenance period of sliding plug door is determined to be 100 000 km.
