This paper describes the vertical dynamic characteristics of a maglev transport vehicle that has permanent magnet suspension with mechanical levitation control. First the fundamental requirements for primary suspension, magnet characteristics and mechanical levitation controller are set up. Then, the vehicle vertical dynamics are analyzed using a two-degree-of-freedom model, where the roughness averaging effect of the undercarriage with a longitudinally distributed magnet is considered. A theoretical study and simulation are carried out to evaluate the effect of the wheelbase and magnet length of the undercarriage on the vertical acceleration of the car body and the guide wheel load, which are used as performance measures. The results show that the difference in averaging effect between the wheelbase of the undercarriage and the longitudinally distributed magnet causes an increase of guide wheel load. A suitable relation between the wheelbase and magnet length is proposed by considering the roughness averaging effect and the pitching motion of the undercarriage.
