Stress and deflection analysis of the PLT-coil using ANSYS computer code

A new PLT-TF Coil deflection and stress analysis is performed using the ANSYS computer code and STIF45 incompatible mode version isoparametric eight node elements. The coil is treated as an assembly of these elements where each turn of copper and epoxy is clearly and separately defined. This model offers the opportunity for turn by turn study of both spiral and circular configurations. Coil behavior due to various boundary conditions, material property changes and loading profiles are calculated, discussed and summarized. Final deflection results are compared with actual measurements which were obtained during the PLT machine power tests. Model inadequacies and possible improvements are discussed and suggested
