Acoustic Fatigue

System noise and vibration characteristics can be random by nature. To accurately address noise and vibration issues, engineers must address these problems from a randomly statistical point-of-view. High acoustical excitations induced by a powerful jet or rocket flow are naturally random and induce random vibrations in the aircraft fuselage, spacecraft launcher fairing panels or satellite. These vibrations cannot actually be determined, but are rather interpreted as power spectral densities or PSDs. In this case, potential induced fatigue damage is random by nature and directly linked to the PSDs of the resulting stress. LMS Virtual.Lab Acoustic Fatigue is a dedicated solution that addresses random acoustic fatigue problems. By integrating Random Vibro-acoustics and Random Fatigue modules, this solution helps engineers understand the random vibro-acoustic behavior of a given structure and predict fatigue hotspots and corresponding fatigue life to optimize design for fatigue performance. LMS Virtual.Lab Acoustic Fatigue handles both structural and acoustic responses using vibro-acoustic results for durability analysis. Working with acoustic responses, the solution supports transmitted and scattered sound due to random structural and/ or acoustical excitations. For structural responses, this solution can calculate vibration amplitudes, as well as support stress recovery by providing stress spectral densities for structural elements based on stress modal vectors obtained by standard FE solvers. From this, engineers can assess critical structural points in terms of vibrations and stress levels and use these for fatigue life predictions.
