The technical progress to manufacture high temperature superconducting bulk material (HTS) provides various possible applications. This involves non-contact linear transport systems and frictionless rotating bearings using the pinning effect in Typ-II superconductors. During the last five years a group of industrial and research partners have developed an innovative magnetic levitation system (SupraTrans) with a permanent magnetic rail and YBCO superconducting bulks in the vehicle. To optimize the levitation and guidance system further investigations in the static and dynamic behaviour have been accomplished and are reported. Comparisons between the statics, the dynamics and the simulation show a very well agreement in all comparable parameters. The conclusions obtained in this research can be summarized as follows: 1) The weight of the levitation part determines the working point of a SMB. Since the overall behaviour such as vertical and lateral stiffness is strongly influenced by the working point, the levitation weight is a crucial parameter for designing the SMB. 2) The verification of the measurement results from the setup for static force and stiffness measurements with the results from the dynamic experimental setup has been accomplished successfully. 3) To describe the SMB by a harmonic oscillator by means of mechanical parameters to investigate the dynamic behaviour was proposed and applied to simulate the dynamic behaviour.
