Experimental Modal Analysis on Automotive Development

In the last years, vehicle vibroacoustics has expanded as a basic and applied research area. Structural dynamic methods and technologies have been used with great success by the automotive industry. Experimental modal analysis is the process of determining the modal parameters (modes, frequencies and damping factors) of a linear system. This work presents the modal analysis of the Amazon family cars in full vehicle configuration (drivable units). A full vehicle represents a more complex system when compared to the body only, due to the systems attached to it, increasing its damping and measurable noise, and including coupled local and global modes.
