Design to acoustics by applying vibroacoustic metamaterials to a vehicle front axle carrier frame

A vibroacoustic metamaterial is applied to the cross bridge component of a vehicle front axle carrier frame of an electric drive train. First, the disturbing frequency is identified by a finite element analysis and second a matching VAMM is designed. The developed prototype is manufactured using 3D-printing and the resonators are tuned and investigated via experiments.
