FIELD TEST AND STATISTICAL CHARACTERISTICS OF WHEEL-RAIL FORCE FOR SLAB TRACK WITH PASSENGER AND FREIGHT TRAFFIC
-
摘要: 客货共线无砟轨道，相较于客运专线，货车轴重的增加势必造成列车荷载的增大，而轨道结构直接承受列车荷载的作用，因而有必要对客货共线无砟轨道轮轨力荷载的统计特征做进一步研究。该文以客货共线CRTS I型板式无砟轨道为研究对象，选取遂渝线蔡家车站和渝怀线鱼嘴2号隧道两个测点，应用IMC动态数据采集系统测取过往客、货车垂向轮轨力。运用轮轨系统耦合动力学理论建立车辆-轨道垂向耦合动力学模型，计算不同车速和不同轨道不平顺激励下客、货车轮轨力，结合实测数据，分析客货共线无砟轨道轮轨力的统计特征，得出以下结论：客货共线无砟轨道轮轨力呈近似正态分布，95%以上客车轮轨力分布于45 kN~90 kN，95%以上货车轮轨力分布于100 kN~150 kN，与实测所得数据基本吻合；客货车轮轨力概率密度曲线随车速和不平顺幅值的增大而逐渐变得“矮胖”，轮轨力分布范围随车速增大和线路状况劣化而逐渐增大，且线路状况对轮轨力分布的影响远大于车速；以1.5倍静轮重和轮轨力最大峰值为控制指标，建议客货共线无砟轨道客车车速控制在180 km/h以下，货车车速控制在100 km/h以下。Abstract: The increase of axle load of a freight vehicle for railways with passenger and freight traffic will certainly lead to an obvious increase of train load. Since the track structure sustains the dynamic load of moving train directly, it is necessary to do further research for statistical characteristics of wheel-rail forces of railways with passenger and freight traffic. In order to measure the vertical wheel-rail forces of the passenger vehicle and freight vehicle on CRTS I slab, two field tests at Caijia station of Suining-Chongqing railway and at Yuzui No.2 tunnel of Chongqing-Huaihua railway were carried out by applying the IMC dynamic data acquisition system. Meanwhile, a vertical vehicle-track coupling dynamic model was established to calculate the wheel-rail forces of a passenger vehicle and a freight vehicle with respect to the different velocities and the irregularity excitations. The statistical characteristics of wheel-rail forces for slab track with passenger and freight traffic were investigated by comparing the computational results with the experimental data. The results show that: a) wheel-rail forces for slab track with passenger and freight traffic were similar to normal distribution, and more than 95% of the values concerning the wheel-rail force caused by passenger vehicles and freight vehicles range in the domain of 45 kN~90 kN and 100 kN~150 kN respectively, which correlates well with the actual experimental observations; b) the probability density curve of the wheel-rail forces caused by passenger vehicle and freight vehicle become fatter and shorter with the increase of velocity and amplitude of irregularity, and thusly, the distribution range of the wheel-rail force will be broaden due to the increase of velocity and the degradation of railway condition, and the latter factor affects the distribution of the wheel-rail forces more seriously than the former's; c) if the 1.5 times of the static wheel load and the maximum value of the wheel-rail force are set as the control indexes, it is suggested that the velocity of passenger vehicle for slab track with passenger and freight traffic should be controlled under 180 km/h, whereas the freight vehicle should be no more than 100 km/h.
