Vehicle Acoustics

The Noise, Vibration and Harshness (NVH) development in automotive industry is a highly diverse research challenge. Our research group contributes to different sectors of this broad field. Investigation topics reach from component level to full vehicle systems. Chassis-, powertrain- and interior noise- phenomena are in the chairs focus. Steering and tire induced vibrations are the main drivers on the chassis side. Electric drives, combustion engines and the related transmissions represent the powertrain field. The interior noise as one of the main target values to evaluate a vehicles comfort level closes the loop from excitation to response.

Automotive systems are continuously increasing their complexity and noise transfer is nonlinear for a large number of cases. Since processes are increasingly digitalized, we are utilizing and improving a variety of tools and methods to overcome the challenging simulation process. Finite-Element-, Boundary-Element- and Machine-Learning-Methods (FEM, BEM, ML) are combined with state-of-the-art component- and full vehicle-measurements in order to achieve the best possible results. The digital prediction of system responses is the common goal throughout the different areas.
