Abstract

There is a main problem that the noise generated in AIR INTAKE SYSTEM may be disgusting. STATISTICAL ENERGY ANALYSIS is a suitable method for acoustical - vibration analysis of structures in high frequency range. In this paper, the AIR INTAKE SYSTEM of an engine compartment is modeled using SEA. The TRANSMISSION LOSS through the intake duct is calculated with importing CAD model and creating subsystems at high frequency range. In order to verify the results, a simple model of double walled cylindrical shell is modeled in Auto-SEA, and the results are compared with those of analytical ones. In addition, comparing the results of fully modeled of intake systems with experimental data available shows a good accuracy of results especially in high frequency range. Furthermore, the influence of inserting POROUS MATERIAL is studied. Finally, the influence of some other parameters such as the thickness of the porous layers on the TRANSMISSION LOSS of the system is investigated.
