Abstract
Either from a legislative point of view or because of OEM demands, the automotive industry is increasingly facing of reducing vibration & noise in the vehicle. More particularly on the engine area, the development of Gasoline and Diesel fuel components based on high pressure pumps, rails, any pipes and injectors are more and more subject of a particular NVH (Noise Vibration and Harshness) attention.
The use of modern digital techniques such as 3D FEM vibroacoustic, leads to use virtual prototyping as complementary to traditional real hardware prototypes development. Among interest, number of iterative loops to reach a best design brings an important value to new product development with an optimized cost.
Basically the core part of virtual prototyping is about a 3D FEM model definition for each component. It is quite challenging to establish these models, as they must mimic the entire physical phenomenon of real structure borne hardware sound in the whole audible frequency range.
Several items allow bringing the most appropriate digital model for NVH study, such as experimental data for correlation, definition of source of loads and definition of boundary conditions. Limitations of models are also identified and allow opening 1 true matter: Should we stay considering only each component separately or as an assembly of parts of a larger system?
In the proposed paper, some methods are going to be reviewed from building the most appropriate models to support virtual NVH prototyping. It leads designing a real product. A particular focus on examples based on high pressure pumps is reported there.
