摘　　要：本文提出一种中低速磁浮列车用悬浮牵引合一系统。该系统基于直线感应电机结构,其短定子三相绕组装在车辆上,次级铁板沿轨道辅设。基于有限元数值方法,对合一系统结构及供电模式进行分析计算,结果表明通过基波电流控制牵引力大小;通过施加同步速谐波电流,来控制直线感应电机初、次级之间吸力大小,达到列车稳定悬浮的目的是可行的。与传统结构比较,这种系统将悬浮、牵引两套系统合一,可提高工作效率,降低列车能耗,减少设备数量,且控制方便,适合中低速磁浮列车工程应用。The paper puts forward a levitation and propulsion control combined system used in mid-low speed maglev trains.This new system is based on the structure of the linear induction motor.Three phase windings of its primary stator are installed on vehicles,and the secondary iron plates are laid along the tracks.The system structure and power supply mode are analyzed with the finite element method.The results show as follows：The magnitude of propulsion forces can be controlled by fundamental wave currents;the magnitude of attraction forces between the primary and secondary sides of the linear induction motor can be controlled by application of synchronization-speed harmonic wave currents;it is feasible for the trains to attain the objective of stable levitation with the combined system.Comparing with the traditional levitation and propulsion control structure of the maglev train,this new combined system serves to raise the operating efficiency,debase the train energy consumption,decrease the number of installed equipment and facilitate convenient controll.It is adaptable to engineering applications in mid-low speed maglev vehicles.
