Steady State Thermal Analysis Of Friction Stir Welded Stringer Panel Of An Aircraft Wing

摘要

Welding is a wide range multistate permanent fastening method of fabrication. Globally welding technology has numerous applications. The present project deals with the calculation of the steady state thermal analysis and fatigue life of the friction stir welded stringer panel. The stringer panel is a device used for supporting the upper and the lower skin of the aircraft wing. The equivalent stresses and life cycles are calculated theoretically referring to many journals, the theoretical inputs are given to the analysis software ANSYS Workbench i.e. heat flux, temperature, and speed of rotation of the friction stir tool. The resultant equivalent stress and the total deformation apart from that the life cycles are also generated. The theoretical values of stress and fatigue life are computed. The best welding conditions are predicted by suitable analysis in ANSYS Work bench software by providing suitable working conditions as inputs.
