Electromagnetic Analysis of Suspended Electromagnet of Medium-Low Speed Maglev Train

通过对中低速磁浮列车走形机构的结构原理分析，将悬浮控制模块合理简化，利用多体动力学仿真软件SIMPACK建立中低速磁浮车辆的动力学模型，对车辆在曲线工况下的运动学特性进行仿真分析。根据仿真结果，利用ANSYS MAXWELL搭建悬浮电磁铁三维分析模型，并作适当简化，对磁极横向偏移时保证悬浮力下的安匝数、导向力和导向刚度进行电磁仿真分析，为磁浮列车悬浮电磁铁参数优化提供理论依据。
By analyzing the structure principle of the bogie of the medium-low speed maglev train and simplifying the levitation control module reasonably, the dynamic model of the medium-low speed maglev vehicle is established by using the multi-body dynamics simulation software SIMPACK, and the kinematics characteristics of the vehicle under the curve condition perform simulation analysis. According to the simulation results, this paper uses ANSYS MAXWELL to build a three-dimensional analysis model of the suspension electromagnet, and makes appropriate simplifications to perform electromagnetic simulation analysis on the number of ampere-turns, guiding force and guiding stiffness under the suspension force, which remains unchanged when the magnetic poles are shifted laterally, which provides theoretical basis for the parameters optimization of the levitation electromagnet of the maglev train.
