Summary: In this paper, a novel hybrid vibro-impact electromagnetic-dielectric generator (VI EDG) embedded into a pendulum structure to form a pendulum-based absorber-harvester (PAH) system is proposed. The PAH system can convert vibration energy into electrical energy and reduce the swing amplitude of the pendulum. The physical model of the PAH system is introduced, and the governing equations involving the dynamical and electrical parts are derived. Experimental validation is carried out to measure the swing motion of the pendulum. The energy harvesting performance of the PAH system is investigated through numerical simulations, and the vibration absorption performance of the VI EDG is discussed.

Summary: This study presents a floating piezoelectric electromagnetic hybrid wave vibration energy harvester that is actuated by a rotating wobble ball. The kinematic equation of the rotating wobble ball under the influence of the wave is established by simplifying the ocean wave model. One notable feature of the proposed harvester is its ability to harvest wave vibration energy using a frequency up-conversion mechanism. Experimental results demonstrate that the hybrid energy harvester can efficiently collect low-frequency wave vibrations and generate electrical power.

Summary: This paper proposes a systematic modeling approach for railway vibration energy harvesting systems (VEHSs) considering the intricate interaction and coupling in the vehicle-harvester-circuit system. An equivalent circuit method is used to establish a model for a rotary electromagnetic VEH, and mechanical friction is considered and optimized to improve prediction accuracy. An efficient energy harvesting circuit (EHC) with a speed-driven maximum power point tracking (MPPT) algorithm is designed to extract and store energy from stochastic vehicle suspension vibrations. The developed system model also takes into account the nonlinearities of the freight wagon and the mechanical interaction with the harvester-circuit module. A performance-enhanced control strategy is proposed to maximize onboard harvestable energy. Experimental results show significant improvements in harvester power and force reduction. The prototype of the whole railway VEHS with MPPT closed-loop control is implemented in the embedded environment, enhancing system robustness and practicality in onboard environments.
