A kind of hybrid suspension system with the electro and permanent magnets based on unequal width structure was studiedto solve the problem of the suspension contact existed in medium-speed maglev trains. By analyzing the electromotive relationship ofthe U-shaped iron, F-shaped rail and air gap using ANSOFT, the model of a suspension system based on the unequal width structure wasestablished. The suspension system was designed and verified on the basis of Zhuzhou maglev test line. Simulation results showed thatregardless of the size of air gap in the new suspension system, the attraction force between the iron and rail always could balance thegravitational force, thereby making zero power control possible.
