Abstract:
OBJECTIVEThe purpose of this study was to establish two-dimensional magnetic field finite element analysis model of cup-yoke-type magnetic attachment for optmizing the design of magnetic attachments.
METHODSBecause the magnetic field of cup-yoke-type magnetic attachment is stable axial-symmetrical, the authors only analyzed two-dimensional magnetic field of 1/2 section. The Maxwell stress between magnet and keeper was integral analyzed using the finite element method, and the attractive force between magnetic attachments was obtained.
RESULTSCompared the value of calculated attractive force with that of examined, the authors found that the procedure veritably reflected influencing trend of variable factors on attractive force, and the value of former one was 10% less than the later one.
CONCLUSIONThis procedure can be used in magnetic field calculation of cup-yoke-type magnetic attachments.
