160km/h中低速磁浮交通轨靴受流仿真研究

Current Collecting Simulation of 160 km/h Mid-low Speed Maglev Rail Collecting Shoe

中低速磁浮交通的车辆牵引供电采用正负极接触轨侧部受流方式。目前,国内中低速磁浮交通最高时速为100 km/h,鉴于磁浮交通作为主城通往市郊的连接线或旅游专用线的重要交通工具,需具备更高时速要求。而接触轨作为唯一和磁浮列车接触的设备,其在满足受流需求下,还应具备高的可靠性。研究采用ANSYS软件建模,搭建接触轨、受流靴仿真模型,受流靴按仿真设定车速运行,完成接触过程的仿真研究,得出轨靴动态接触压力仿真数据,为中低速磁浮列车进一步提速到160 km/h提供轨靴受流适应性理论基础。

The power supply of mid-low speed maglev traffic adopts the side current collection mode of positive and negative pole contact rail. At present, the highest speed of mid-low speed maglev traffic in China is about 100 km/h. As an important means of transportation between the main city and suburbs, or for the tourism purpose, maglev train needs to run at a higher speed. Being the only equipment in contact with maglev train, the contact rail should not only meet the demands of current supply, but also have high reliability. In this study, ANSYS software is used to build a simulation model of contact rail and current collecting shoe, the running speed of the latter is set by simulation. After the completion of contact process simulation, the dynamic contact pressure simulation data of rail and current collecting shoe are obtained, which provide a data basis of the adaptability theory for rail shoe current collection of the maglev train in further speed-up to 160 km/h.
