Numerical and conceptual design of vibroacoustic metamaterial solutions for structural vibration reduction in launcher components

This work deals with numerical and conceptual design of vibroacoustic metamaterial solutions for structural vibration reduction in launcher components. The adjustable and compact design of vibroacoustic metamaterials based on a local resonance effect leads to an attractive and flexible solution especially for lightweight thin-walled structures in space industry. An inverse unit cell modelling approach is used to for the numerical design of a demonstrator including multiple tuned vibration absorbers (TVA).
