Zusammenfassung Structure-borne road noise dominates the cabin of modern vehicles, especially in the case of electric vehicles (EVs). Several RNC prototype systems based on analogue accelerometers are available in the market. So far the placement of these sensors has been based either on random optimisation methods or on a rule of thumb that at least 3-6 reference signals per wheel are necessary. An improved method for selecting sensor locations and optimising their performance is demonstrated in this paper. The method takes into account suspension and axle locations that are important for NVH/CAE prognosis, TPA and modal analysis of structure-borne road noise.
