Modal criteria for optimization of structures through active structural acoustic control

Abstract

To cite this version:Sébastien Besset, Louis Jezequel. Modal criteria for optimization of structures through active structural acoustic control. International Journal for Numerical Methods in Engineering, Wiley, 2010, 82 (12) Abstract This paper deals with modal criteria allowing optimization of structures through structural acoustic control (ASAC) based on the independent modal strategy control (IMSC). The aim of the paper is to propose efficient criteria allowing to process optimization of structures by determining the most important modes to control considering only the location of the excitation on the structure. A generalized modal synthesis is used to study the coupled fluid-structure system. Modal criteria are proposed in order to determine the best choice for the controlled modes used in IMSC method. The way the ASAC will be applied is not discussed in the paper. Numerical simulations are computed to show the efficiency of the method, considering a simple vibroacoustic structure.

Local active control for an exterior fluid‐structure interaction problem

“…They consider the in‐vacue model plate and the fluid‐load acting on the plate. Besset and Jézequel in deal with modal criteria allowing optimization of structures through ASAC based on the independent modal strategy control. Brancatti et al in present a novel boundary element formulation for sensitivity analysis of local active noise control.…”
