Summary:

Nowadays, NVH aspects in automotive sector are becoming very important. Components have to respect, other than strength targets also acoustic targets, in a way of reduce noise emission of the full vehicle. While vibration aspects have been sufficiently explored by virtual methodology but also by experimental one, the same it is doing, in recent years, for Noise aspects. Automotive engine manufactures are implementing CAE technology and methodology to simulate the acoustic characteristic of components and to optimize geometry, material and others parameters in order to match customer acoustic targets. This paper tell about numerical methodology to estimate the acoustic vibration of an Intake Manifold component and how to use that methodology to reduce noise radiation. Vibroacoustic analysis for different Intake Manifold are going to be presented, showing results and how they are managed to match customer targets
