Advanced numerical analysis for vibration characteristics and ride comfort of ultra-high-speed maglev train

Development of new electromagnetic suspension–based high‐speed Maglev vehicles in China: Historical and recent progress in the field of dynamical simulation

“…The analysis of Maglev vehicle dynamics involves different disciplines including classical vehicle system dynamics, magnet dynamics, Maglev control design, and power electronics. Whereas for magnet dynamics and control design usually self‐generated codes are used, standardized software tools for mechanical system modeling, such as the commercial codes SIMPACK 34,35 or ADAMS, 36 are also used for modeling the Maglev vehicle mechanics. Worth mentioning is also the research code NEWEUL 37 and its successor Neweul‐M 2 38 developed at the Institute of Engineering and Computational Mechanics for deriving the symbolical equations of motion for multibody systems and used in numerous studies 26,28,39 .…”

System dynamics in structural strength and vibration fatigue life assessment of the swing bar for high‐speed maglev train

“…Schmid et al 4 proposed an electromagnet modeling approach to improve mechatronic models and the simulation efficiency of a maglev control system for TR 09 maglev vehicles. Ha et al 5 constructed flexible car-body models using the finite element (FE) method and updated the MBS model of Shinkansen L0 maglev vehicles to a rigid-flexible-coupled model to improve the solution accuracy. Wang et al 6,7 and Xu et al 8 considered the elastic vibration of track girders, viaduct piers, and bridges in the rigid-flexible coupled model of Shanghai high-speed maglev vehicles, and the curved-path-induced vibration responses of the vehicle were obtained and used to examine the effect of cross-section parameters for curve routes.…”
