Kurzfassung
The European Ariane 5 launcher is powered by two solid boosters and a cryogenic liquid core engine. A full analysis of the thermo-mechanical loading of the nozzle extension tubes of this engine has to model the production, the welding and the cyclic loading of the tubes during the hot run. In the current extended abstract, only the welding of the nozzle extension tubes is considered. At DLR Lampoldshausen, no dedicated welding analysis tool is available. Therefore, the welding of the nozzle extension tubes was modeled by a general purpose Finite Element code (ANSYS). A fully transient 3d thermal analysis of the welding provides the time dependent thermal boundary condition for the follow-on quasi stationary structural analysis of the welding of the nozzle extension tubes. This 3d elasto-plastic structural analysis is based on the von Mises yield function and rate dependency according to Peirce.
