Structural-Acoustic Analysis of Air Duct Using FEM
Original language description
Tone noise radiated through the inlet of a turbofan is generated mainly by rotor and stator interactions at subsonic regimes and by the shock waves generation at transonic fan tip speeds. The generated noise may reach very high sound pressure level and ultimately it can lead to a fatigue failure of air inlet duct. In this study structural-acoustic analysis of the aircraft duct is presented. The acoustic pressure field of the ducted air is determined by finite element method using the boundary condition of acoustic pressure in the rotor cross-section, which is determined on the basis of the analytical equations. A structural-acoustic analysis of the composite air duct is solved as fully coupled and also as sequentially coupled. On the basis of the structural-acoustic finite element analysis, stress and strains histories of the duct walls are determined.
