“…Low frequency vibration has been recognized as a major source of pollution in today's industry because of the multiple hazards it poses. 6) Long-term exposure to low frequency vibration can cause serious damage to human health. Of note, the relatively low intrinsic frequencies of large buildings, heavy instrumentation and transportation infrastructure make them more susceptible to low frequency vibration hazards.…”

Low-frequency vibration poses a great danger to both industrial production and human health. Therefore, the development of efficient low-frequency vibration reduction structures remains a focus of academic and engineering research. In this paper, a novel low-frequency vibration reduction local resonance phononic crystal (LRPnC) plate with a square spiral beam LRPnC design is proposed. Through finite element simulation, the band structure and vibration characteristics of the LRPnC are first analyzed. On this basis, a gradient LRPnC plate with rainbow trapping effect is constructed by gradient arranging unit cells with different structural parameters to achieve broadband vibration reduction. Finally, the vibration reduction performance of the designed structure is experimentally verified. The finite element analysis results show that the designed gradient LRPnC plate can provide more than 20 dB of transmission attenuation over the full frequency range of 20 to 200 Hz. And the experimental results are consistent with the simulation results.

“…These mechanisms facilitate the absorption of mechanical energy from low-frequency vibrations and its transfer into a high-frequency range for efficient conversion. Impact has been employed as a means of frequency upconversion [45][46][47][48][49][50]. The impact-based PEH comprises two components: a low-frequency component that absorbs mechanical energy, and a high-frequency harvester that converts the mechanical energy into electrical one.…”

In this study, a novel piezoelectric energy harvesting (PEH) system featuring triple frequency-up converting is proposed. The system comprises a piezoelectric cantilever and two stoppers. When in contact with the stoppers, the cantilever transitions into a high-order vibration mode, leading to the reversal of voltage outputs. The frequency-up converting effect is achieved by multiple mode switches occurring during a single cycle of motion. Experimental results demonstrated the significant ability of the proposed system to achieve triple frequency-up converting across a broad frequency range. Furthermore, three pre-bias displacements were introduced to assess the frequency-up converting characteristics of the PEH. The system exhibited a maximum ratio of triple and essential frequency components reaching up to 8.86. A maximum root-mean-square (RMS) power output of 3.03 mW was achieved.

The study deals with the experimental examination of a magnetorheological (MR) damper control system with vibration energy harvesting using a specially engineered electronic unit (EU). Unlike a typical MR damper control system, which requires an external energy source, the developed system is powered exclusively by energy extracted from a vibrating structure (mechanical system with one-degree-of freedom) and processed through the EU. The work describes the structure and functions of the EU, presents the test rig and the control algorithm implementation, and discusses the test results of the control system under harmonic kinematic excitations of low frequency range.
