摘要
为分析轨道板结构在环境温度、太阳辐射与风荷载等因素共同作用下所产生的温度梯度效应,搭建了轨道板温度场数据采集系统,对某运营线路轨道板不同深度的温度与周围气象参数进行实时数据同步采集,研究了气象参数对轨道板内部温度场的影响.基于实测气象参数,利用ANSYS软件对轨道板进行三维瞬态建模,并与实际测得轨道板温度场进行比较,结果显示模拟数据精度较高,可为道路养护维修提供参考.
In order to analyze temperature gradient effect of track plate＇s structure produced by the combination of environmental temperature, solar radiation and wind loads, data acquisition system of track plate＇s temperature field was built. Synchronous acquisition of real-time temperature of track plate at different depth and ambient meteorological parameters were carried out, and the influence of meteorological parameters on the track plate internal temperature field was studied. Based on the measured meteorological parameters,a three-dimensional transient finite element model was established by ANSYS software for track plate and the simulated data were compared with the measured data. The result shows that the accuracy of simulated data is higher, which can provide a reference for road maintenance.
