An M-shaped buckled beam for enhancing nonlinear energy harvesting

Kunming Chen et al.

Summary: This paper proposes a bistable energy harvester with an M-shaped buckled beam aiming to achieve high-performance piezoelectric energy harvesting under low excitation. Compared with the original monostable M-shaped beam, the proposed harvester can easily maintain large-amplitude interwell oscillation and offer a wider operation bandwidth in a lower frequency range. Numerical and experimental results show that the acceleration threshold required for interwell oscillation can be decreased by reducing the buckling level in bistable configurations, which provides higher voltage and wider operation bandwidth in sweep frequency excitation. Additionally, the performance of the monostable configuration with a softening behavior is better than that with a hardening behavior.

Summary: This paper proposes an auxetic centrifugal softening impact energy harvester (ASIEH) to achieve high energy output at ultra-low rotational frequencies.

Dingxin Leng et al.

Summary: This paper proposes a semi-active X-shaped vibration isolation system with magnetorheological elastomer (MRE) based on its field-controlled variable properties. The system demonstrates the ability to tune its stiffness for effective vibration mitigation in random low-frequency excitations. The theoretical modeling, static analysis, and dynamic equation of the proposed system are presented. The study investigates the influence of key geometrical parameters and field strength on system characteristics and presents tunable frequency-shift properties. Experimental results show a reduction of 22.5% in the displacement of the isolated objective under single frequency harmonic excitations with a field strength of 0.7 T. Furthermore, under double-tone external loading, the semi-active control reduces the displacements of the excited and isolated objectives by 63.95% and 18.77% respectively compared to the passive-off state. The proposed MRE-based XSVI system demonstrates outstanding isolation performances compared to other systems.
