ANALYZING STRUCTURAL DESIGN RELATIVE TO VIBRATIONAL AND/OR ACOUSTIC LOADING

摘要

A computer-performed method of designing a structure. User-selected design parameters are input to a parametric model of the structure. Boundary conditions and load conditions are applied to the model to determine a response of the structure to the conditions. Based on the load conditions, an analysis method is selected. The modeled response is analyzed using the selected analysis method to obtain power spectral density (PSD) values for the model. The PSD values are averaged over a user-selected frequency range to evaluate the design parameters for acoustic transmission loss. This method provides a high degree of flexibility in formulating structural design analyses.
