摘要:
针对车辆检修作业风险管理问题，论述利用已有故障信息和维修经验进行风险评价的过程。利用作业条件危险性评价法，对车辆检修作业风险进行分析和评价，对发生事故/事件的可能性、暴露于危险环境的频繁程度和事故/事件所产生的后果 3 个参数， 分别制定等级划分和分值设置表，并在此基础上形成事故/事件的风险值评价表。以长春轻轨 3 号线某次列车分离事故为例进行风险识别和风险分析，并制定相关管控措施。作业条件危险性评价法可用于数据不充分条件下车辆检修作业初步风险分析，评价结果可作为开展故障诊断和调整维修规程的技术依据，但需要关注评估人员经验不足等因素可能带来的偏差。
Abstracts:
Aiming at the risk management issues on rolling stock maintenance，the process of risk evaluation by the fault data and maintenance experiences are discussed. The risk of maintenance operation is analyzed and evaluated by LEC（likelihood，exposure, consequence）method from aspects of likelihood of accident，exposure of staff in dangerous environment and the consequences，the grade classification and the score setting table are formulated respectively. The risk identification and risk analysis based on a vehicle accident on Changchun LRT Line 3 are analyzed，and corresponding control measurements are produced. The results show that LEC method is suitable for the preliminary risk analysis of rolling stock maintenance under the condition of insufficient data，and the evaluation results can be used to make decisions for accurate fault diagnosis and adjustment of maintenance procedures. Meanwhile，issues on probable errors caused by the inexperienced assessors require special attentions.
