Description
Summary:	The presented work addresses an industry-oriented design process of vibroacoustic metamaterials for automotive components with enhanced acoustic properties. The procedure involves numerical prediction of the resulting dynamic behavior in regard to stop band characteristics as well as manufacturing techniques suited for series production. Vibroacoustic metamaterials from sheet metal are developed for future implementation to a vehicle door to create a stop band in the frequency region around 600 Hz. Production is done using punching and bending techniques, followed by an experimental verification of the stop band characteristics.
