The vertical motions of road and rail vehicles can be treated jointly again. The investigations of the vertical motion provide a basis for the optimization of the driving comfort, and the driving safety as far as road vehicles are concerned. The contact forces in wheel contact patches most important for the longitudinal and lateral motions are directly affected by the vertical motion according to the rolling contact laws. The fundamental principles of a vehicle suspension can be completely studied by a model with two vertical degrees of freedom. However, for a more detailed analysis more complex models can be used, too. For magnetically levitated vehicles the active suspension control has to be considered, too. For wheeled vehicles actively controlled suspensions are also of increasing interest.
