Work was carried out to define the optimum position of component support points to minimize the eddy current stresses. The components are idealized with linear or non-linear beam models depending on the eddy current force distribution. Then the position of the maximum value for the bending moment as a function of the support locations is estimated in order to obtain minimum moments and therefore stresses. It is shown that a factor of up to approximately 30 in stresses can be gained by careful choice of support positions. The near optimum location is independent of the component material, orientation, size and type of disruption.
The work has been applied specifically to the design of the JET NI Duct tiles. It resulted in negligible stresses in the inconel support subframe and minimum stresses in the copper tiles.
