“…Yang et al [7] presented a comprehensive review on vibration energy harvesting and vibration suppression technologies, and discussed the potential applications in aerospace/marine/transport engineering and health monitoring and vibration control etc. Huang and Yang [110] made numerical exploration on combination of vibration absorption and energy conversion of MEH via a dynamical model of a 2-dof dynamic vibration absorber. They found that a tristable electromagnetic energy harvester could induce a rapid attenuation in the residual kinetic energy of the primary system (excited by an impulse) thus realize vibration suppression.…”

“…Bibo et al [25] studied the effect of nonlinearity on the performance of the monostable/bistable galloping energy harvesters. Huang et al [26] proposed a 2-DOF tristable dynamic vibration absorber and energy harvester, finding that a tristable electromagnetic energy harvester has favorable energy trapping capacity and energy conversion performance under broadband and lowamplitude vibrations. Wang et al [27] experimentally found that the maximum output power of a tristable gallopingbased energy harvester reached 0.73 mW and the cut-in wind speed was 1 m/s.…”

In the past few years, different kinds of structural nonlinearities, such as external magnetic interaction and multistable structures, have been introduced into galloping energy harvesters to enhance energy harvesting efficiency. However, since the galloping-based piezoelectric energy harvester (GPEH) is a self-excited system, the conventional impedance matching method that is widely used in vibration energy harvesters is no longer valid for it. Therefore, the power characteristics of the nonlinear GPEH are still an open question to be solved. To this end, this paper is motivated to derive the approximate analytical solution of a monostable galloping-based piezoelectric energy harvester through the harmonic balance method and impedance matching theory. The analytical maximum power, power limit, and critical electromechanical coupling are studied from the perspective of the influence of structural nonlinearity on the power performance. Firstly, the approximate analytical solutions of output power, power limit, optimal resistance, and critical electromechanical coupling coefficient are derived. The accuracy of the analytical solution is verified by numerical simulation. It is found that the influence of structural nonlinearity on the power characteristics of the nonlinear GPEH is quite different under different wind speeds. After that, the power characteristics of the system under different wind speeds and different coupling conditions are investigated. The results showed that the maximum power of the system can be increased by introducing stiffness nonlinearity under low wind speed and weakly coupled configuration. Even more, the system can be shifted into a strongly coupled system when the nonlinearity is enhanced to a certain level. Reasonable design of stiffness nonlinearity can effectively reduce the critical electromechanical coupling, which indicates that stiffness nonlinearity is a feasible and effective way to improve the power performance of low-speed wind energy harvesting.

“…Chiacchiari et al (2017, 2019) investigated the potential benefit of the bi-stable element coupled to a directly excited primary system for converting broadband and low-amplitude vibration energy such as single and repeated impulses into available energy, and explored snap-through regimes, namely periodic cross-well, aperiodic (chaotic) cross-well, and intra-well oscillations. Huang and Yang (2021a, 2021b) studied and evaluated the energy conversion performances and energy trapping capacity of a tri-stable DVA under impulsive excitations and harmonic vibrations in comparison with their counterparts of a bi-stable DVA, and proposed a tunable bi-stable energy harvester to scavenge the undesired vibration energy and simultaneously convert it into available energy. Nguyen et al (2019) developed detailed models for both mono-stable and bi-stable magnetic spring-based vibration energy harvester configurations, where the bi-stability is caused by introducing a cluster of peripheral solid magnets.…”

This paper introduces an energy conversion inspired vibration control methodology and presents a representative prototype of tunable bi-stable energy converters. This work is concerned on improving energy conversion and absorption performance of tunable bi-stable clustered energy conversion inspired dynamic vibration absorbers (EC-DVAs). The deterministic parametric analysis of the energy transfer performance of clustered EC-DVAs is conducted. The nonlinear energy capture behaviors including transient energy transfer and snap-through motions are studied. It can be uniformly understood that the excellent energy transfer and conversion efficiency can be achieved by modulating the length ratio from 0.6 to 0.8. It is found that clustered EC-DVAs with four uniform cells and constant length ratio σ = 0.8 can obtain significant energy conversion and targeted energy transfer performance without requiring tedious active regulation when the system is subjected to wide-amplitude impulsive scenarios. Therefore, the proposed tunable bi-stable system composed of clustered EC-DVAs with state-of-the-art adaptive control strategies is a potential alternative for energy reuse and vibration suppression of mechanical components exposed to kaleidoscopic impulses.
