Abstract :
The structural analysis of the IGNITOR machine load assembly has been performed taking into account the friction coefficients at the interfaces between the significant components. The finite element ANSYS model was used to analyze the nonlinear mechanical behavior of the structure. The calculation shows stresses within the allowable limits at the operating temperature. Interlaminar shear stresses values on TFC insulation have been validated by the results of test performed by Ansaldo. Two full size of Ignitor TFC turns have been manufactured by Kabel Metal to qualify the fabrication process and the hardening of the material OFHC. Several samples of the cooling channel were machined to validate the Electron Beam (EB) welding process
