Vehicle noise and vibrations Noise and vibrations in vehicles has been one of the most challenging issues since 70’s, when most of the car manufacturers started developing and modelling special techniques and specific materials to predict, measure and control the NVH (Noise, vibration, and harshness) environment inside and outside the vehicle. The increasing lightness of vehicles, the customer comfort and satisfaction, the durability of the materials has driven this research at the beginning, thanks to the contemporary dramatic development of signal processing techniques and instruments, FEM (Finite Element Modelling) modelling and low-cost sensor availability. The development of commercial modal analysis software took start exactly for these purposes and quickly became a standard for noise and vibration analysis of body in white cars and complete vehicle including later special applications for interior noise, acoustic absorption, and isolation, damping materials up sound quality and many other specific applications. A Vehicle must be designed at its early stage with respect to the Noise and vibration framework. Its design and analysis is quite often a recursive task and model must be tuned on the basis of real measurements, so that prototypes must provide the feedback for design and early modelling and modification. The overall task is complex and includes noise and mechanical vibration source modelling and measurements, path transfer and propagation, material characterisation and selection, fluid-structure interaction, numerical and experimental modal analysis. The Vehicle noise and vibrations course is intended to give a general knowledge and overview of the entire topic, under the different points of view of modelling and measurement, with respect to noise, vibrations and materials adopted to mitigate and control the behaviour of the final product delivered to market. Elements of modelling, measurement and fitting are given with emphasis to the specific application field as well as real examples and solved problems. The techniques currently adopted for the characterization of NVH materials, and their effects on the overall NVH behaviour, are described and explained using simulation and measurement.
