高速磁浮列车导向系统的有限元法分析

FEM Analysis of High-speed Maglev Guiding System

介绍了电磁型高速磁悬浮列车的导向系统,采用电磁场有限元法对导向电磁铁进行数值计算分析,得到导向力的大小与激励电流和气隙间隔之间的关系。最后进行了磁场测量试验,实验测量数据和有限元计算的结果吻合,证明了该分析的正确性。并为高速磁浮列车导向控制系统的设计提供了重要的理论依据。

EMS high-speed maglev guiding system is introduced in this paper.Using FEM of Electromagnetic field,guiding force is calculated;the relationship between guiding force and source current,air gap is got.At last,we did the experiment of magnetic field.The experiment data accords with the result of FEM calculation.,which proofs the validity of analysis. These provide theory gist for the design the control system of high-speed maglev train.
