At the same time, a maglev system is undoubtedly preferable to air travel in terms of energy requirements and environmental protection. Against the background of recent plans in China to develop a new 600~km/h high-speed maglev train, this dissertation deals with the mechanical modeling and numerical simulation of the dynamics of high-speed maglev trains, which, like the \tr{}, are based on the electromagnetic suspension principle.
With the development of suitable simulation models of the coupled vehicle-guideway system using the elastic multibody systems approach, this dissertation makes a valuable contribution to the simulation-based development process of future high-speed maglev trains.
In addition to modeling, it contributes to technological progress with simulative investigations gaining insights into various aspects of coupled vehicle-guideway dynamics.
A rigid multibody vehicle model is coupled with an elastic guideway by moving forces in a two-dimensional longitudinal-section model, implementing an infinitely long elastic guideway.
For numerous questions, two-dimensional models are sufficient and even desirable to keep the model complexity and the computation times low.
Some aspects of interest, however, require a three-dimensional model, such as magnet failure scenarios or driving along curves.
To allow for investigating those issues, the last part of the dissertation focuses on developing a comprehensive three-dimensional model of one single vehicle section.
