Abstract

After the realization of the GVT (Ground Vibration Testing) campaigns on the AIRBUS A350 XWB 900 in 2013, the ONERA-DLR specialized joined team performed the GVT of the A320 NEO Pratt & Whitney powered in July 2014. The specifications of this test were particularly oriented to the updating of a renewed FEM (Finite Element Model) of this new version of the A320. Concerning the GVT, the latest improvements on developed methods and tools were applied, making the completion of the test successful in 7 measurement days for 2 mass configurations. Concerning the GVT, the very short time devoted to this campaign imposed by a strict and busy planning from the program leaders required to reinforce in one hand the test techniques and methods, mixing PSM (Phase Separation Methods) and PRM (Phase Resonance Methods) and to optimize in the other hand the workflow and the data deliveries to meet the challenging test requirements. This paper describes the processes followed and the methods used in this particularly hard context and how those contributed to the successful achievement of this challenging test campaign. Concerning the FEM updating, an optimized process has been applied to update the renewed FEM, especially focusing on the updated components such as pylons, engines, wings and sharklets. This process - including correlation analysis, tuning FEM then validating tuned FEM w.r.t GVT - has provided a means to tune FEM within a short time to support clearance of first flight test.
