Structural intensity assessment of experimental structural response data from aircraft structures
Year: 2025
Type: conference-paper
Abstract: Structural intensity allows the user to visualize the vibrational power flow in structures.With appropriate post-processing, it is also possible to identify sinks and sources in vibrating structures.This circumstance ideally allows us to perform assessments of possible placements of countermeasures.While it is trivial to calculate the structural intensity via numerical simulations, this is not the case for measurement data, as crucial information regarding non-measurable degrees of freedom is missing.This publication overviews a methodology to acquire structural intensity vector fields from measurement data, and the results of two structural intensity assessments based on measurement data of aircraft structures are presented.Furthermore, a comprehensive outlook is given that focuses on a novel path identification approach currently in development and other crucial factors that need investigation to conduct structural intensity assessments at a state-of-the-art level for research and industry.
