In order to improve the performance of vibration energy harvesters over a broad frequency range, this paper proposes a use of piezoelectric nonlinear energy sink (NES) for energy harvesting from ambient vibrations. A standard rectifying direct current (DC) interface circuit is considered to generate DC power from the piezoelectric NES under harmonic excitation. Harmonic balance method is used to obtain the dynamic response and energy harvesting performance of the proposed piezoelectric NES, verified by the equivalent circuit simulation. Analytical and numerical results show that the design, by applying NES, improves the efficiency of energy harvesting without increasing the vibration of the primary structure in a broadband manner. The effects of the electromechanical coupling, excitation level and load resistance on the magnitude and bandwidth of the output DC power are investigated.

The harmonically excited structure coupled with the nonlinear energy sink (NES) and a piezoelectric harvester is investigated. The complexification-averaging method is developed to analyze ordinary differential equations which also include one first order differential equation. Effects of varying parameters for the piezoelectric harvester on the saddle-node bifurcation and the Hopf bifurcation are explored. Analytical results of the amplitude–frequency response curves are verified by the numerical evidence. Global bifurcations for NES parameters are presented. Comparisons of periodic results for bifurcation diagrams are performed both numerically and analytically as well as their stable ranges. The integration of nonlinear vibration suppression and energy harvesting is discussed. The output voltage, power, displacement transmissibility, and average energy are calculated to explore the integration. Quasi-periodic responses near the resonance frequency contribute to effectively reducing the resonant amplitude and improving the bandwidth of energy harvesting, as well as targeted energy transfer. Results confirm that the integration of vibration suppression and piezoelectric energy harvesting can be enhanced by adjusting cubic nonlinearity.

Nonlinear energy sink (NES) is employed to passively reduce vibration transmission in this study. A two-degree-of-freedom system, comprising a primary structure coupled with a grounded piezoelectric NES possessing essential nonlinearity, is investigated for both harmonic force excitation and base excitation. The piezoelectric NES acts as not only a vibration isolator but also an energy harvester when connected to an alternating current circuit. Approximate analysis is carried out by the harmonic balance method and validated by numerical solutions using ODE45 in Matlab and equivalent circuit simulation. The effectiveness of the nonlinear vibration isolation system is evaluated by the force (displacement) transmissibility defined as the root-mean-square ratio of transmitted force (displacement) to the excitation force (displacement), which is compared with that of its linear counterparts. Output voltage of the piezoelectric transducer is also derived. By and large, it is found that the piezoelectric NES could reduce the force (displacement) transmissibility while collecting electric energy efficiently in a relatively broad frequency range.

The potential of absorbing and harvesting energy from a two-degree-of-freedom airfoil using an attachment of a nonlinear energy sink and a piezoelectric energy harvester is investigated. The equations of motion of the airfoil coupled with the attachment are solved using the harmonic balance method. Solutions obtained by this method are compared to the numerical ones of the pseudo-arclength continuation method. The effects of parameters of the integrated nonlinear energy sink-piezoelectric attachment, namely, the attachment location, nonlinear energy sink mass, nonlinear energy sink damping, and nonlinear energy sink stiffness on the dynamical behavior of the airfoil system are studied for both subcritical and supercritical Hopf bifurcation cases. Analyses demonstrate that absorbing vibration and harvesting energy are profoundly affected by the nonlinear energy sink parameters and the location of the attachment.

Good Agreement

Using nonlinear energy sink absorber (NESA) is a good countermeasure for vibration suppression in wide board frequency region. The nonlinear normal modes (NNMs) are helpful in dynamics analysis for a NESA-attached system. Being a primary structure, a cantilever beam whose modal functions contain hyperbolic functions is surveyed, in case of being attached with NESA and subjected to a harmonic excitation. With the help of Galerkins method and Raushers method, the NNMs are obtained analytically. The comparison of analytical and numerical results indicates a good agreement, which confirms the existence of the nonlinear normal modes.
