Some hybrid numerical-experimental integrated approches are presented and tested in order to obtain accurate predictions of the vibroacoustic field emitted by an 8.5 cc/rev external gear pump. FFT (Fast Fourier Transform) acceleration spectra were experimentally acquired (B&K Pulse system) in a few positions of the external gear pump casing for some operating conditions. Different computation methodologies are applied in order to estimate the dynamic response of the structural/acoustic FEM (Finite Element Method) models.

Abstract
Some hybrid numerical-experimental integrated approches are presented and tested in order to obtain accurate predictions of the vibroacoustic field emitted by an 8.5 cc/rev external gear pump. FFT (Fast Fourier Transform) acceleration spectra were experimentally acquired (B&K Pulse system) in a few positions of the external gear pump casing for some operating conditions. Different computation methodologies are applied in order to estimate the dynamic response of the structural/acoustic FEM (Finite Element Method) models.File in questo prodotto:
