M. Rassaian, J.-C. Lee, G. K. Young, A. E. Landman

This patent presents a parametric modeling method that connects acoustic and vibration tests using a conversion factor from finite-element analysis. By applying pressure and base excitation to a parameterized panel, peak responses define a scalar that converts sound spectra to shaker-table inputs. The approach enables automated meshing and geometry optimization, cutting the cost and complexity of acoustic fatigue testing.
