Abstract
Analysis of vibro-acoustic systems is challenged by their highly non-linear and complex properties, especially for the damping structure. So, an approximate response surface method (RSM) method is utilized to analysis the effect of design parameters on the sound radiation from a vibrating panel. A simple case study was illustrated to demonstrate the capabilities of the developed procedure. In details, sound radiated from vibrating panel with a point force excitation has been analyzed by numerical method. The structure-born noise problem is approximated by a series of second-degree polynomials. Three analysis objectives are considered, namely, mean quadratic velocity, sound radiation power and system loss factor. In this way, the trend of sound radiation varying with design parameters can be obtained conveniently and effectively.
