After the discussion of vehicle models and models for support and guidance systems, guideway models are treated now for ground vehicle systems. Depending on the kind of the vehicle and design aspect, different tasks exist. The vehicle dynamicist dealing with the design of road or rail vehicles regards the guideway as rigid in a first approximation. He is interested in the disturbances, which affect the vehicle from the guideway. The structural dynamicist, who designs bridges, pillared guideways or rails, regards the vehicles as moving loads and is interested in the elastic deformations of the structural elements. In contrast to this partial system consideration, in the case of a strong dynamic interaction between vehicle and guideway, the behavior of the vehicle - guideway system has to be analyzed and optimized as a whole. Such strong dynamic interactions exist e.g. for rapid magnetically levitated vehicles on pillared guideways. The consideration of the guideway into the system optimization has also great importance for economic reasons. A good portion of the entire investment - for magnetically levitated transport systems about 75% - is accounted for the guideway.
In the following models for elastic guideways as well as disturbance models for rigid guideways are developed. It is shown that in both cases linear mathematical relations arise. Therefore, both models can be superposed, if necessary.
