Numerical analysis of the superconducting magnet outer vessel of a Maglev train by a structural and electromagnetic coupling method

The harmonic magnetic field generated by the ground coils can cause vibration of the superconducting magnet, which must be reduced as it generates heat in the liquid helium temperature range. Therefore, it is important for the design of lighter magnets to exactly estimate the electromagnetic force on the superconducting magnet. Some causes of the vibration were analyzed by the structural and electromagnetic coupling FEM-BEM method. (C) 2001 Elsevier Science B.V. All rights reserved.
