Vibroacoustic properties specify among others the quality of vehicles and contribute to customer satisfaction. In the early design phase, a finite element (FE) analysis is usually carried out to predict and design vibroacoustic properties. Nevertheless, the inevitable lack of information adversely affects the model-based prediction like vibroacoustic vehicle properties. For instance, a deterministic one-point model parameter like Young’s Modulus, which ignores the variance due to manufacturing tolerance, leads to among others an incomplete determination of real vibroacoustic behavior of the vehicle in FE simulation. At this point, uncertainty is only partially taken into account in vehicle vibroacoustic. This paper contributes to mastering uncertainty in model-based prediction of vibroacoustic vehicle properties.
