Abstract: To study the influence of forced guiding mechanism on medium and low speed maglev vehicle, the refined dynamic models of both 4-module and 5-module medium and low speed maglev vehicles are established. The dynamic response differences when 4-module and 5-module medium and low speed maglev vehicles passing curve routes with or without the forced guiding mechanism are comparatively analyzed, the action mechanism of the forced guiding mechanism under different unbalanced accelerations is also studied. Results show that when the unbalanced acceleration is large, the forced guiding mechanism plays a guiding role; in the opposite condition, the forced guiding mechanism plays an anti-guiding reaction. When the anti-guiding is functioning, the rotating arm of the forced guiding mechanism in 4-module medium and low speed maglev vehicle is subjected to a greater force, then the middle mobile slide can be split to reduce the force. Under strong disturbances such as crosswinds, the forced guiding mechanism has positive significance for the curve passing performance of medium and low speed maglev vehicles.
