A theoretical and simulation study on the vertical dynamic characteristics of a Maglev transport vehicle that has a permanent magnet suspension with mechanical levitation control is described in this paper. The vertical dynamics of the vehicle, including pitching motion, is formulated first. We examine the influence of the pitching motion of the undercarriage on the guide wheel load, which is one of the performance measures of the vehicle, theoretically. The running simulation is carried out to confirm theoretical results. The results show that the pitching motion of the undercarriage has a great influence on the guide wheel load, and the suitable relation between magnet length and wheelbase length is discussed from the viewpoint of reducing the guide wheel load. We point out that a small control lever ratio causes a lack of pitch stiffness and damping of the undercarriage and that small size of the undercarriage is effective in reduction of the guide wheel load.
