Abstract:
In the low frequency range (under 200 Hz) the Finite Element Analysis (FEA) is the current standard design tool for virtual acoustic (and vibration) prognosis. In the middle frequency range, between 200 Hz and 800 Hz, neither the FEA nor the SEA approaches are able to provide realistic result predictions, leading to the existence of the so-called mid-frequency gap. This paper introduces the so called SEA-like approach in which an inverse SEA model is deduced using a standard FEA vehicle floor...     »
