The permanent magnet suspension (PMS) transportation system utilizes the magnetic repulsion between the on-board permanent magnet and the permanent magnetic rail to achieve levitation. Understanding and mastering the relationship between the magnetic force of the permanent magnet and its spatial pose parameter are crucial for designing the running gear of the maglev train and track structure. A three-dimensional magnetic field finite element model was developed for the on-board permanent magnet and the permanent magnetic rail based on the PMS transportation system of Xingguo County. The magnetic force on the on-board permanent magnet was calculated under different levitation gaps, lateral offsets, pitching angles, rolling angles, and yawing angles. The variation patterns of levitation force and lateral force of the on-board permanent magnet with respect to these five pose parameters were analyzed, as well as their correlation degree. The results indicate that the magnetic force of the on-board permanent magnet is primarily influenced by the levitation gap and lateral offset, with a greater impact from the yawing angle and minimal effect from the pitching angle and rolling angle. Within the specified range of parameter variations, the ratios of the minimum and maximum values of the levitation force to the rated levitation force are approximately 0.75 and 1.16, respectively. In addition, the maximum value of the lateral force reaches 50.42% of the rated levitation force. The direction of the lateral force of the on-board permanent magnet aligns with its lateral offset direction, while the yawing torque aligns with its yawing angle direction. Consequently, a guiding device is necessary for the PMS system to prevent lateral bobbing and yawing movements of the on-board permanent magnet.
