Abstract:In this paper, optimization design for minimization sound radiation from thin plate based on ADS (Acoustic Design Sensitivity) analysis is studied. Firstly, the velocity distribution of structure surface is solved by analytical method and the surface sound pressure is computed by Rayleigh integral respectively. The sound radiation power of structure can be expressed as a positive definite quadratic form of the Hermitian by impedance matrix. Then, the relationship between the sound radiation power and thickness… Show more
