Influence of vibrations in HTSC-PM bearings - Computation and experiments
The force of high-T-c superconductors (HTSCs) in an inhomogenous alternating magnetic field has been investigated. Using a new experiment set-up, the dynamic response of the permanent magnet superconductor interaction has been evaluated for low frequencies and low amplitudes of vibration. A numerical model to simulate the previously observed behaviour has also been developed. The calculation method, based on the critical state model, has been extended, taking into account the influence of flux flow.
