Authors Abstract
Content
A general approach for minimizing radiated acoustic power of a baffled plate excited by broad band harmonic excitation is given. The steps involve a finite element discretization for expressing acoustic power and vibration analysis, analytical design sensitivity analysis, and use of gradient-based optimization algorithms. Applications to rectangular plates and an engine cover plate are presented. Thicknesses are chosen as design variables.
