Fluid-structure modal analysis

It is proposed to investigate convenient coupled systems modeling for modal analysis of bounded coupled systems such as internal structural acoustics. Appropriate reduced symmetric matrix models arc constructed using zero-frequency static solutions. In this respect, attention is paid to tile behaviour of tile fluid-structure equations with regards to their validity for zero frequency static limit. The Structural Mechanics and Coupled Systems Laboratory of the Conservatoire National des Arts et Metiers is involved in hybrid active/passive control of vibrations and transient responses using piezoelectric and viscoelastic devices for beams, plates and axisymmetric shells and coupled fluid-structure systems.
