| description | Based on the analysis on structural and dynamical characteristics of movers in linear induction motors and permanent magnet synchronous motors, this paper explored the change rules of mover motions of swaying, bouncing, rolling, yawing and pitching in the starting, coasting, and braking states, by developing the dynamical models with the multi-body dynamics simulation software for ultra-high-speed (1 000 km/h) electromagnetic propulsion devices respectively in the above two drive types. The final results show that the normal force applied on the induction mover facilitates automatic lateral alignment of the mover and resistance to lateral impact, while inhibiting rolling and yawing of the mover. In the scenario of the permanent magnet mover, the normal force from the motor aligns with the direction of mover deviation. Consequently, the mover moves close to the guideway under the impact of lateral irregularity without restraining rolling and yawing effects. Due to the vertical irregularity of the guideway, the induction motor mover experienced notable vertical vibration and impact, while the vertical component force applied by the motor on the permanent magnet mover mitigates vibration to some extent. This paper concludes that running states significantly affect the vertical response and pitch motion of the two types of movers, and the maximum vertical displacement, acceleration, and impact force all occur during braking for both. |
