Simplified reduced-scale modelling of vehicle interior noise

Structure-borne vehicle interior noise is an important issue affecting not only drivers' and passengers' perception of vehicle quality, but also their health and safety. Therefore, the significance of the matter requires continuous efforts to improve sound quality in vehicle compartments. The existing research models of vehicle interior noise are either too simple, which makes them unable to provide concrete solutions, or too complex, which makes them difficult to interpret. In this regard, the main objective of the current thesis is to bridge this gap between existing very simple analytical and very complex numerical models for vehicle interior noise analysis. This thesis proposes a new methodology of vehicle interior noise analysis based on theoretical and experimental studies of simplified reduced-scale models of real vehicles. [Continues.]
