摘要：

目前国内针对中低速磁悬浮电磁兼容问题的研究很少,而电磁兼容对列车的正常运行具有重要意义。研究了直线电动机对中低速磁悬浮列车的电磁干扰问题。对直线电动机工作时横向端部产生的磁场进行了分析,并建立了磁场的数学模型。结合工程实际,用有限元仿真软件搭建了长沙磁浮快线中低速磁浮列车直线电动机的电磁场仿真模型,通过仿真得到直线电动机横向端部磁场的空间分布和变化趋势,结合仿真结果和工程实际分析直线电动机产生的电磁辐射对车底设备的电磁干扰。

Abstract:

At present, there are few studies on the electromagnetic compatibility of the low-speed maglev train in China,and electromagnetic compatibility is of great significance to the normal operation of trains.The electromagnetic interference of linear motor on the low-speed maglev train on electromagnetic compatibility was studied.The magnetic field generated at the transverse end of the linear motor was analyzed,and the mathematical model of the magnetic field was established.According to the engineering practice, the electromagnetic field simulation model of the linear motor of the low-speed maglev train in Changsha Maglev Express Line was built by using the finite element simulation software.The spatial distribution and changing trend of the magnetic field at the lateral end of the linear motor were obtained by simulation.The electromagnetic interference of the electromagnetic radiation produced by the linear motor to the vehicle bottom equipment was analyzed combining with the simulation results and engineering practice.

Key words: electromagnetic compatibility (EMC), low-speed maglev train, linear motor, electromagnetic radiation
