摘要
利用超导材料的零电阻,大载流特性,可解决常导电磁悬浮(EMS,Electromagnetic Suspension)系统中存在的线圈耗能严重,磁体易发热等问题。提出了一种“高温超导+常导”结构的混合EMS系统,其中,超导线圈置于U型铁芯中间,提供列车所需主要悬浮力,常导线圈置于U型铁芯两端,起调节控制作用。通过对该系统进行建模,并利用ANSYS Maxwell 2D仿真模块对其悬浮力进行分析,验证系统的性能与可靠性。结果表明,所提出的混合模型相较常导EMS模型悬浮性能具有较大提升,且常导线圈具有很好的调节控制效果,能够满足磁浮系统的高稳定性要求。
Based on the zero resistance and large current carrying characteristics of superconducting materials,the problems of serious coil energy consumption and easy magnet heating in EMS(electromagnetic suspension)system can be solved.In this work,a hybrid EMS system was proposed,in which the superconducting coil was placed in the middle of the U-shape core to provide the main suspension force required by the train,and the normal conducting coil was placed at both ends of the U-shape core to regulate and control the train.By modeling the system,and using ANSYS Maxwell 2D simulation module to analyze its suspension force,the performance and reliability of the system were verified.The results show that the levitation performance of the proposed hybrid model is better than that of the EMS model,and the normal conducting coil has good control effect,which can meet the high stability requirements of the maglev system.
