The testing equipment for fuselage panels of aircrafts at the IMA GmbH Dresden is designed for fatigue tests as a preliminary stage to the full aircraft fatigue test. The natural disturbance at the boundaries of these panels is going to be minimized due to a well-adapted test rig design. The main advantage of this testing scenario lies in the lower testing effort and is therefore used to assess new design or material concepts. A numerical simulation of this process by means of a finite element (FE) analysis is the most important tool to model the actual setup and to adjust the loads in terms of a varying panel configuration. The objective in this project is to extend the current testing strategy to panel configurations with an open set of geometrical parameters. The consideration of cut-outs or new materials as well as a new variety of fuselage diameters and non-circular cross sections gets into focus. The results coming from these analyses can be used to draw conclusions for the loading situation of future detailed structure tests having refinement and sub-modelling strategies of an FE model in mind.
