Application of vibroacoustic metamaterial to compensate continuum resonance in powertrain mounting systems for electric vehicles

The concept of vibroacoustic metamaterials applied to elastomeric engine mounts is proven. An engine mount is optimized using a virtual design process, prototypically produced, and experimentally validated. It is shown that vibracoustic metamaterials are a valid design for passive, nonfluidic engine mount with beneficial behavior with respect to the vibration transmission.
