To study the fault condition of medium-low speed maglev vehicle in its electromagnet failure and suspension force loss and the influence on its vehicle dynamic performance,a dynamic model of medium-low speed maglev vehicle with three suspension frames was established,and the dynamic indexes of linear operation and curve passing performance were simulated and analyzed.The results show that electromagnet failure has little influence on stability index and guide clearance,but grealy affects suspension clearance,suspension module nod angle and passing speed.When electromagnet fails,vehicle speed should be limited at 60 km/h in the straight section and 38 km/h in the R100 curve section.
