Traditional mathematical design methods for vibration absorbers decrease in efficiency when external vibration changes. A novel self-learning tuning method is proposed to suppress variable frequency vibration by utilizing experimental vibration data.

Summary: Magneto-mechano-electric (MME) generator converts magnetic energy into electrical energy via mechanical strain/stress mediated magnetoelectric coupling effect. In this work, a hybrid multi-mode MME device is proposed with broadened bandwidth and enhanced energy harvesting performance by developing the constitutive equation of MME structure. The designed hybrid generator includes three power generation units: piezoelectric energy harvesting (PEH) unit, electromagnetic energy harvesting (EEH) unit, and magnetostrictive energy harvesting (MEH) unit. Moreover, the corresponding energy harvesting management circuit is designed for these units to achieve the maximum harvest of magnetic field energy. At the magnetic field of 5.57 Oe, the maximum output power of the three generating units are 0.71 mW (PEH), 1.694 mW (EEH), and 0.27 mW (MEH), respectively. The proposed hybrid generator can provide a stable power for temperature and humidity sensors integrated with Bluetooth wireless communication technology by harvesting stray magnetic field energy, and has the potential to power wireless sensors.

Summary: This paper proposes a novel combined negative stiffness mechanism (CNSM) that combines attractive magnetic NSM (ANSM) and repulsive magnetic NSM (RNSM) in parallel. By counteracting the stiffness nonlinearities of the ANSM and RNSM through parallel configuration, the CNSM achieves a wider displacement region with reliable linear stiffness. An analytical model of the CNSM is established and verified through simulation and parametric studies. Static and dynamic experiments demonstrate the effectiveness of the CNSM in generating high linear stiffness and lowering the resonance frequency.

Summary: A novel hydro-pneumatic near-zero frequency vibration isolator with high-static and low-dynamic stiffness is proposed, featuring a nonlinear damping strategy implemented by fluid damping mechanism to enhance vibration isolation performance. Increasing all types of damping can reduce the occurrence of amplitude sudden-jump in primary resonance, while square type damping based on fluid mechanism can suppress resonance response effectively. The study provides insights into how nonlinearity effects of each damping dominate vibration isolation transmissibility, showing the advantageous application of the novel isolator in practical scenarios.

Summary: This paper focuses on enhancing the QZS isolator by introducing tunable nonlinear inerter (TNI) to improve low-frequency isolation performance. Analytical calculations, stability analysis, and numerical simulations were conducted to compare the isolation performances of the QZS isolator and the QZS-TNI isolator. Results show that adding the inerter considerably suppresses the bending trend of the transmissibility curve, leading to a wider frequency range of isolation and a lower peak transmissibility.
