摘要
为进一步加强铁路运营安全管理,研究轨道平顺性保持的制约条件,首先以某铁路的轨道测量仪数据和综合检测列车数据为研究基础,分析轨道几何尺寸偏差与车辆/轨道相互作用关系,判别相关基础设施变形、列车运行、养护维修等综合作用下的轨道不平顺影响因素;然后结合养护维修工作实际情况,总结针对不同病害处置采用的典型养护维修方法;最后系统说明轨道作为铁路基础设施的基本组成部分、与机车车辆轮对直接接触的重要部位,其平顺性对于列车安全、平稳、达速运行的重要作用。结果表明:不同轨道不平顺对机车车辆平稳运行影响各异;轨道不平顺受基础设施变形、轮轨作用、养护维修方式等因素影响;轨道不平顺可通过科学合理的养护维修得以控制。
For the sake of strengthening safety management of railway operations,the restriction conditions for maintaining track regularity were studied.Firstly,based on test data of a certain railway collected by track measurer and safety inspection car,track geometric dimensioning and interaction relationship of vehicle and track were analyzed,and factors that affect track irregularity under comprehensive action of related infrastructure deformation,train operation,maintenance and repair were identified.Then combined with actual situation of maintenance and repair,the typical maintenance methods for different track diseases were summarized.Finally,it systematically explained that the track,as a basic part of railway infrastructure and an important part in direct contact with the wheel set of locomotive and vehicle,its regularity played an important role in safe,smooth and fast train operation.The results show that different track irregularities have various effects on the safe and stable operation of locomotive and vehicle,that track irregularity is affected by many factors such as deformation of infrastructure,interaction of vehicle/track and maintaince mode,and that track irregularity can be controlled by scientific and reasonable maintenance and repair.
