Numerical and Experimental NVH Testing of Vehicle Components – from Simple Part to Complex Assembly

Abstract

Increased demanding in the fields of noise pollution, human comfort and health finds its prints in the development of automotive components. The paper presents general problems of noise and vibration in the vehicles. Main sources and transfer paths are identified. The sound quality – psychoacoustic aspects are also described. In the second part of the article, authors presents an example of numerical and experimental approach to the undercarriage components testing in the field of noise and vibrations problems. Presented examples leads through the basic investigations of particular component to the investigations of complex subassemblies.
