Project Objectives

The principal objective of this FP6 STRP project is developing a vibration control technologyto enable higher performance, less energy consuming and lighter weight structural systems. Vibration control technology involves reducing detrimental vibration in flexible structures by active and passive procedures. Passive procedures include structural optimisation, applying passive damping treatments to a structure and passive isolation techniques. Active procedures include the use of control systems to couple sensor measurements to actuator forces via distributed or centralized processing. Active control is used to isolate a system from outside disturbances or focus directly on the structure to actively damp vibrations. Developing an adaptive structure technology should address the deferent blocks in such a system in a systematic fashion.   CASSEM ambition is to define the "best" models and techniques permitting to model, simulate, and validate the new developments for a more efficient vibration control. This project will not only have a scientific aim but also a direct industrial application.

Five specific S&T objectives of the project are defined and summarised as follows:

• Improved characterisation of electro-mechanical properties of materials and structures (including direct and inverse identification techniques)
• Advanced multi-physics (mechanical, electric, thermal) modelling of multifunctional multilayered (elastic, viscoelastic, piezoelectric) composite structures.
• Innovative (non-linear) vibration (evolutionary) control strategies for active, passive and hybrid multifunctional structures.
• Optimisation of the location and size of the passive (viscoelastic), active (piezoelectric) and hybrid (passive-active) damping treatments.
• Experimental validation tests on representative structures for relevant applications.
