Investigations About the Experimental Application of PEDE_M for the Reproduction of a Structural Response to a Turbulent Boundary Layer Excitation

Any transportation vehicle is inevitably subjected to turbulent air-flows, resulting in different challenges, including structural vibrations, noise emissions, structural fatigue, and passenger discomfort. These complex, multidisciplinary issues necessitate the development of efficient solutions for predicting and managing the effects of stochastic loads, such as Turbulent Boundary Layer (TBL) excitation, on diverse engineering structures. In literature, several alternative methodologies have been introduced, all aimed at providing an “off-line” experimental approach to predict vibrational responses w ithout the need for wind tunnel testing. This work investigates into another innovative method known as the Pseudo-Equivalent Deterministic Excitation method (PEDEM)- It analyses the evolution of PEDEm over the past decade since its inception at the inaugural FLINOVIA conference in 2013. The study details a methodology for the experimental application of PEDEM. named X-PEDEM.along with its inherent properties and advantages. By subjecting this methodology to both experimental and numerical testing, it aims to validate its efficacy. X-PEDEm offers the potential to predict the structural responses to turbulent air-flows and to manage the experimental set-ups needed for a final testing of any designed structure.
