| Abstract: | The magnetic force and mechanical stress of the magnet system of magnetic confinement plasma thruster are calculated by using Finite Element Analysis(FEA) software ANSYS about the coupled electromagnetic-structural field,which is based on the magnets parameters of the magnetic confinement plasma thruster.In this paper,We have calculated the axial magnetic compressing force in nodes of mid-plane and the force among magnets for the superconducting magnets.We have compared the variation of the mechanical stress between the magnets with and without the stainless steel wires for reinforce. |
