Coombs, TA and Cardwell, DA and Campbell, AM (1997) Dynamic properties of superconducting magnetic bearings. IEEE Transactions on Applied Superconductivity, 7. pp. 924-927. ISSN 1051-8223Full text not available from this repository.
The potential use of YBa2j as an active component in a magnetic bearing is being investigated. Although the load bearing capacity is high and increases with the square of the magnetic field trapped, the stiffness is low. Both the stiffness and the lévitation height are a function of the loading history of the bearing. At Cambridge we have been investigating the effects of dynamic loading such as single large excursions from steady state loads and cyclically applied loads such as vibrations. Since a superconducting bearing has little inherent damping cyclic loads applied at or near its natural frequency can have catastrophic effects. The information being gathered at Cambridge will be used to enable these effects to be mitigated in the bearing design process. © 1997 IEEE.
