“…The NES-giant magnetostrictive-piezoelectric also performs International Journal of Energy Research well in suppressing nonlinear aeroelastic response and harvesting energy [175]. NES-giant magnetostrictive-piezoelectric has also been applied to the subsonic aeroelastic system, where the energy harvesting performance of the system is affected by periodic motion and instability [176]. The proposed piezoelectric energy harvester consists of a partially covered piezoelectric cantilever beam, as shown in Figure 20; the electromechanical coupling distribution parameter model of the device was as follows [177]:…”

Vibration control has been of great interest to scientists and engineers for many years. Although linear vibration absorbers have been shown to be effective in mitigating vibrations at specific frequencies, their vibration reduction effect is usually limited to a narrow frequency bandwidth. Nonlinear energy sinks have attracted attention due to their better vibration reduction effect over a wider frequency bandwidth. In practical applications, the nonlinear energy sink devices can effectively absorb, dissipate, and convert energy from broadband excitation, so as to achieve vibration reduction and energy harvesting. However, research on energy harvesting based on the nonlinear energy sink is less mature than in linear systems. Multiple parameters of device design (e.g., damping size) affect the actual performance of the nonlinear energy sinks, but there is no exact method to simplify the design of the multiparameter nonlinear energy sinks. Since it is more difficult to implement electromagnetic and electrostatic energy harvesters, more research has focused on piezoelectric energy harvesters. This paper summarizes the research on the nonlinear energy sink and energy harvesting technology, including the introduction of the nonlinear energy sink, energy harvesting based on the nonlinear energy sink, and its application in various fields of energy harvesting. The paper also summarizes some important methods for solving the dynamical equations, as well as their advantages and disadvantages. The conclusions provide an outlook on the subsequent research of the nonlinear energy sink technology, such as the introduction of piezoelectric materials with high energy density, the benefits of balanced vibration suppression and harvesting of vibration energy, and the self-tuning of parameters in complex environments. It provides a powerful reference for the popularization and application of energy harvesting technology based on nonlinear energy sinks.

“…The study of geometric nonlinear aeroelasticity differs from general aeroelasticity [1] from the theoretical aspects as follows: One is the structural geometric nonlinear theory, which mainly addresses the static and dynamic analysis of the structure under large deformation [2][3][4]; The other is the study of surface aerodynamic theory [5], which mainly addresses the boundary condition dependent deformation state aerodynamic calculation method under large deformation conditions of the structure [6]; The third is the study of the structural/aerodynamic interface coupling method [7,8], which mainly investigates the multidimensional interpolation problem applicable to large deformation in space. The problem of subsonic aeroelasticity of plates focuses on the fluid-structure coupling between the structure and the airflow [9,10]. The variety of parameters, such as mass, damping and stiffness of the structure under the action of subsonic airflow affects the critical instability and nonlinear vibration characteristics of the structure [2,11].…”

The chaotic motion behavior of the rectangular conductive thin plate that is simply supported on four sides by airflow and mechanical external excitation in a magnetic field is studied. According to Kirchhoff 's thin plate theory, considering geometric nonlinearity and using the principle of virtual work, the nonlinear motion partial differential equation of the rectangular conductive thin plate is deduced. Using the separate variable method and Galerkin's method, the system motion partial differential equation is converted into the general equation of the Duffing equation; the Hamilton system is introduced, and the Melnikov function is used to analyze the Hamilton system, and obtain the critical surface for the existence of chaos. The bifurcation diagram, phase portrait, time history response and Poincaré map of the vibration system are obtained by numerical simulation, and the correctness is demonstrated. The results show that when the ratio of external excitation amplitude to damping coefficient is higher than the critical surface, the system will enter chaotic state. The chaotic motion of the rectangular conductive thin plate is affected by different magnetic field distributions and airflow.
