Vibroacoustic analysis for NVH vehicle development
KFB Acoustics

Revolutionary vibroacoustic analysis reveals how engine excitation and road roughness at low speeds cause structural elements like doors, roofs and windshields to resonate at natural frequencies. These resonances amplify low-frequency noise (boom effect) inside the cabin, affecting passenger comfort.

This study employs an acoustic dynamometer in a semi-anechoic environment with rough road shells and a 3D laser vibrometer integrated with a seven-axis Kuka robot embedded with Robovip software for precise vibration measurements.

Real-time data acquisition and FEM simulations correlate experimental results with predictive modeling, optimizing noise control strategies and enhancing vehicle design. Find out more at KFB's booth.
