Modeling of a beam structure with piezoelectric materials: introduction to SSD techniques

Abstract

Purpose

To provide a model that allows testing and understanding special damping techniques.

Design/methodology/approach

The finite element modeling takes into account the piezoelectric coupling. It is used with a non linear electrical circuit. The approach leads to an accurate tool to observe the behavior of the non linear damping techniques such as synchronized switch damping.

Findings

The model has been validated by comparison with Ansys® but the CPU time required for the model is around one hundred times shorter.

Research limitations/implications

The proposed model is 1D and the assumptions to use it are not verified for all structures.

Practical implications

The authors obtain a useful tool for the design of damping structures (for example to find the best localisation of the piezoelectric patches and to test electrical circuits).

Originality/value

The model is used for the design and conception of damping as well as for harvesting structures.
