摘　　要：为提高轨道交通车辆转向架的使用效率,减少维修的费用,需对其维修计划进行优化。依据更新收益理论,将单位周期内平均安全运行的维护费用最低作为决策目标;根据时间延迟理论,建立转向架维修计划优化模型,基于根据故障记录数据和预防维修检查数据确定时间延迟分布函数;然后运用极大似然法估计出模型参数,求解最优维修周期。最后将所建模型应用于某地铁维修计划的案例研究中,对优化结果与既有维修计划进行比较分析,以验证模型的有效性。研究发现,应用时间延迟模型并结合成组维修,能减少车辆转向架23%的维修成本,对制定转向架维修计划有指导意义。In order to improve the efficiency of bogies of railway transit and to reduce the maintenance cost,it is necessary to optimize the maintenance scheduling.According to the renewal reward theory,the objective of this study is the minimization of average maintenance cost per unit cycle for safe operation.On the basis of the delay time theory,this study develops an optimized maintenance scheduling model for the bogies of railway transit.Based on the failure records and preventive maintenance inspection data,this study develops the delay time distribution function related to maintenance scheduling and a maximum likelihood method is used to estimate model parameters and the optimal maintenance period.Finally,this model is applied to test a subway maintenance plan as a case study.A comparative analysis between optimization results and existing maintenance scheduling is carried out and used to validate the model.The results show that the maintenance cost of the bogies of the rail transit vehicles reduces by 23% when the optimized delay function is applied and combined with the group preventive maintenance.This study may serve as a reference for planning maintenance scheduling of rail vehicle bogies.
