Abstract: This article shows an efficient method with a high industrial
applicability to design piezoelectric smart structures for dynamic
applications. This method allows sizing structures with requirements of dynamic
displacements. The first step of this method consists in extracting dynamic
reduced models from Finite Element simulations which will enable us to obtain a
model for any structure, whatever its complexity, as opposed to analytical
modeling methods. These models are computed for a set of design parameters.
Then a meta-model, which is a simplified descriptive model of other models, is
computed as a surface response model that expresses the design objectives and
constraints as a function of the design variables. The combination of the
results stemming from the meta-model allows working out the optimal values of
the design parameters. The main advantage of the proposed method is to enable
the quick design exploration of structures. As an example, the method is
applied to a flexible structure whose dynamic displacements need to be
controlled in bending and twisting. The theoretical results are validated in
the end by experiments.
