Abstract: The impact of a moment excitation on the vibrational and acoustical response of a fluid-loaded system containing a structural discontinuity is examined. The response metric of interest is the acoustic power radiated from a semi-infinite plate supported in a rigid baffle. The impact of a moment excitation located near a locally reacting distributed-mass discontinuity as well as near the simple supports is examined. Numerical results show that the addition of a moment component can have a dramatic impact on the radiated acoustic power. Both the magnitude and phase of the moment relative to the force can impact the radiated acoustic power.
