Abstract
The main objective of energy harvesting is to capture the energy present in the environment and transfer it to the various available electronic devices. The objective of this research project is to study the dynamic behavior of an energy harvesting system using a piezoelectric transducer applied to an aeronautical structure in flutter condition, with nonlinear stiffness. The mathematical model for dynamic analysis of a flexible wing structure under forcing conditions described will be analysed through numerical simulation. The influence of nonlinear stiffness in the system is analysed by quantifying the mechanical and electrical power in the system. Also, the influence of nonlinear terms on the flutter speed is studied.
