Description

The coil is modelled as a circular beam on elastic foundation. The elastic foundation allows us to take into account the reaction provided by the wedging effect of the coils and the turn over (or intercoil) structure. From the known solutions for a single force acting on such a beam, the authors obtain the formulas for an arbitrary cos ntheta variation of a distributed force. By applying Fourier expansion of the in-plane loads and external reaction forces (as provided by a central bucking cylinder), we can calculate displacements, bending moments, normal and shearing forces. Bending moments in circular coils are reduced when only a small fraction (1/5) of the net inward force is taken up by a central cylinder
