Abstract:
A computer program media, embodying a program of instructions executable by a computer to perform method steps to enable the computer to simulate a structural-acoustic system to determine the dynamic response of the structural-acoustic system over a broad range of frequencies, the method comprising the steps of:wavenumber partitioning a design of the structural-acoustic system into large-scale behavior and small-scale behavior;deterministically determining the large-scale global behavior associated with long wavelength deformations and low wavenumbers;statistically determining the small-scale local behavior associated with short wavelength deformations and high wavenumbers; andpredicting sound, vibration and stress response levels and quantitatively evaluating design changes to modify those response levels for the structural-acoustic system based on results from said deterministical and statistical steps.
