Abstract
The DIANA project aims studying “Development & Integration of a Unified Approach for Structure Borne Noise Analysis”. The project was led by LMS Engineering (Belgium) which collaborated with the research centres of FIAT (CRF, Italy) and Renault (RNUR-DE, France). Other members in the consortium were MIRA (UK) and the Technical University of Bielefeld. Ford Germany acted as sponsor and provided testvehicles.
The first objective of the project included the investigation of advantages, disadvantages, sensitivity to boundary conditions and limits of confidence of several classical techniques in the field of structure borne noise analysis. These techniques were amongst others: single input transfer path analysis, principal component analysis and mount testing.
At the other hand new techniques have also been elaborated. They were related to algorithms for indirect force determination, tire domain principal component analysis and advanced mount testing.
Finally, the different techniques have been integrated into two global methodologies: Engine Noise Analysis and Road Noise Analysis. This investigation has been implemented in software code.
