“…Worth mentioning is also the research code NEWEUL 37 and its successor Neweul-M 238 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 Moreover, also worth mentioning is the software package TR.Mechatron 28 Nowadays, dynamic simulation models are an integral part of the Maglev vehicle development process. Thereby, the simulation models scale from, for example, single magnet consideration 40 through multibody system models 41 to coupled mechatronic models of the whole vehicle, 34 customized in each case for the specific research question.…”

High‐speed Maglev is a cutting‐edge technology brought back into the focus of research by plans of the Chinese government for the development of a new 600 km/h Maglev train. A Chinese‐German cooperation with industrial and academic partners has been established to pursue this ambitious goal and bring together experts from multiple disciplines. This contribution presents the joint work and achievements of CRRC Qingdao Sifang, thyssenkrupp Transrapid, CDFEB, and the ITM of the University of Stuttgart, regarding research and development in the field of high‐speed Maglev systems. Furthermore, an overview is given of the historical development of the Transrapid in Germany, the associated development of dynamical simulation models, and recent developments regarding high‐speed Maglev trains in China.

“…The vehicle model is based on the descriptions in [5,6], representing a detailed two-dimensional rigid multibody model of the maglev vehicle Transrapid mapping the heave-pitch motion in the xz-plane. Left and right side (y-direction) of the system are summed up.…”

“…Elastomer element couplings, represented by linear spring-damper combinations in the model, connect the car bodies. The car bodies are supported on the levitation chassis by the soft secondary suspension, which is realized by air spring rockers at the real vehicle, see [6], for example. Their purpose is the decoupling of the car body dynamics from the higher frequency vibrations of magnets and chassis.…”

“…Some publications focus on the bending of an elastic beam representing the guideway but simplify the vehicle by a point mass or single constant force [2,3,4]. Others exploit a detailed vehicle model, but the guideway is modeled by rigid elements [5,6]. In [7,8,9], these approaches are combined by a rigid multibody vehicle crossing either a short series of elastic guideway elements or a single one, respectively.…”

“…The idea of a guideway of infinite length represented by a finite number of guideway elements is already discussed in [10] but not elaborated in detail. Furthermore, as pointed out in [11], a more detailed vehicle model as, for example, described in [5,6] is desirable to obtain accurate results.…”

For magnetic levitation transport systems with pillared tracks, detailed simulation models of the coupled system of vehicle and guideway offer a valuable contribution to find a tradeoff between stiff/heavy guideway elements, required to keep disturbances small for the controller, and low material consumption. This work provides a novel model of a detailed rigid multibody Transrapid maglev vehicle with three sections moving along an infinite periodically pillared elastic guideway mapping the two-dimensional heave-pitch motion of the vehicle and the elastic bending of the guideway elements. The infinite guideway is realized by moving system boundaries, i.e., the same few Euler-Bernoulli beams representing the current track segment are used repeatedly to form an infinite sequence of guideway elements. The equations of motion of the elastic beams and the rigid multibody vehicle are obtained from the multibody modeling and simulation toolbox Neweul-M 2 . A detailed magnet model in combination with a model predictive control scheme are used for the first time in a large maglev vehicle model in this contribution. All model components are combined and coupled in a Simulink model. Simulation results show more severe overshoots and oscillations of the guideway deflection below the vehicle the faster the vehicle passes, which is resulting in bigger control errors and magnet motions at the rear end of the vehicle compared to the vehicle mid and front. Therefore, in contrast to previous presumptions, the most critical situations are to be expected at the rear end magnet, not at the front end.
