Research Institution
Prediction and enhancement of vehicle interior noise due to high frequency excitation, based on computer simulation, allows the application of the technology at the early stage of design process thereby improving the quality and reducing the cost. Traditionally, Statistical Energy Analysis (SEA) has been used for this purpose. Modeling of SEA is rather complex and requires high level of analyst expertise as well as occasional testing of the product's components. In this proposal, a comprehensive Energy Finite Element Analysis (EFEA) software will be developed for the evaluation of vehicle interior noise. Since the low frequency noise and vibration modeling is traditionally performed using finite element method, the development of an EFEA software will provide a unified framework for the both the low and high frequency noise and vibration analyses.
