摘要
在地铁牵引系统中,供电接触网能够产生电磁场,进而对一定范围内的磁性物体产生干扰。论文将基于有限元法,对列车不同的运行状态及情境进行不同的磁场分布影响分析,通过不同磁场空间分布的计算与模拟结果,记录不同供电方式下的借鉴点,并对北京市地铁特定区间接触网进行仿真,得出不同可行方法。
In the subway traction system, the power supply contact network can produce electromagnetic field, and interfere with a certain range of magnetic objects. In this paper, the influence of different magnetic field distribution on different running states of the train is analyzed based on the finite element method. Through the calculation and simulation results of the different magnetic field spatial distribution, recording reference points of different power supply modes, and simulating the contact network of Beijing subway, different feasible methods are obtained.
