2012 (English)In: PROCEEDINGS OF INTERNATIONAL CONFERENCE ON NOISE AND VIBRATION ENGINEERING (ISMA2012) / [ed] Sas, P; Moens, D; Jonckheere, S, 2012, 4051-4060 p.Conference paper (Refereed)
A set-up is developed for panel-trim measurements with panel boundary excitation, in order to get a physicalunderstanding of the coupling behaviour between vehicle body and trim layer. Structural excitation in themid-frequency range (150-1000 Hz) is investigated. The construction of the set-up and its global featuresare discussed. Furthermore, a Finite Element model is described, and validated against experimental results.There is good agreement, both quantitatively and qualitatively, between measurements and predictions up to1kHz.
