Abstract
Traction, suspension and guidance are characteristics of core electromagnetic performance of high-speed maglev. When the vehicle passes through curves or uneven ground, it is prone to generating significant three-dimensional (3-D) force fluctuations, which have a significant impact on the safety and stability of the maglev. This paper will discuss the effects of transient motion states on the suspension force, traction force and guidance force of maglev. First, general topology and 3-D distribution of electromagnetic forces of system is described. Then, force expressions in 3-D state are developed analytically taking into account the body translation and rotation. Lastly, the variation of force during the roll, pitch and lateral deviation under conditions are tested. The relevant conclusions indicate that the multi-degree-of-freedom motion of the vehicle will change the fluctuation values of 3-D electromagnetic forces, necessitating a magnetic levitation power device with a relatively large electromagnetic stiffness value, the design of a magnetic levitation power device requires a relatively large electromagnetic stiffness value.
