This paper describes the influence of the guideway surface roughness on the vertical motion of a transport vehicle that has a permanent magnet suspension with mechanical air gap control. The roughness averaging effect of the undercarriage with a longitudinally distributed magnet is evaluated by a two-degree-of freedom (2DOF) model with a filter, which is equivalent to the roughness averaging effect. The results show that the difference in the averaging effect between the wheelbase length of the undercarriage and longitudinally distributed magnet causes the increase of the guide wheel load, and that the suitable magnet length is about 1.6 times the wheelbase length. By a funning simulation, it is also shown that the proposed 2DOF model can express vertical vehicle motion effectively when pitching motion is relatively small.
