摘要
基于重载铁路工务维修历史数据和轨道动态检测数据,以提高大型养路机械捣固作业维修经济性为目标,提出了利用综合评价指数在提高线路质量和降低维修成本的矛盾关系中寻求平衡。基于改良型轨道质量指数MTQI,提出了以线路品质指数表征捣固后的线路质量。以某重载线路区段为例,计算并对比了单插不稳定/人工测量/09⁃32型车和单插+单插不稳定/人工测量/09⁃32型车两种模式下的最佳捣固阈值和捣固时机。结果表明,单插+单插不稳定/人工测量/09⁃32型车模式下线路质量保持时间更长,捣固效果和维修费用能够达到更好的平衡。
Based on the historical data of track maintenance and track dynamic detection data of heavy haul railway,aiming at improving the maintenance economy of tamping operation of large maintenance machinery,this paper proposed to use comprehensive evaluation index to find a balance between improving railway quality and reducing maintenance cost.Based on the improved track quality indexMTQI(machine tamping quality index),the railway quality index was proposed to represent the railway quality after tamping.Taking a heavy haul railway section as an example,the optimal tamping threshold and tamping time were calculated and compared under two modes of single plug unstable/manual measurement/09-32 vehicle and single plug+single plug unstable/manual measurement/09-32 vehicle.The results show that under the mode of single plug+single plug instability/manual measurement/09-32 vehicle,the railway quality can be maintained for a longer time,and the tamping effect and maintenance cost can achieve a better balance.
