As railway transportation rapidly expands, operational safety, including regular inspection of
wheel polygonal wear, rail fastener clip failure, and rail corrugation, becomes increasingly …

With the growing interest in smart materials, the utilization of shunted piezoceramics for
dynamic vibration control has gained significant attention due to their unique characteristics …

An electromagnetic vibration energy harvester with a 2: 1: 2 internal resonance (IR) is
proposed, allowing for the simultaneous activation of two IRs within the system in order to …

Purpose With the rapid development of rail transit, it is becoming more demanding to
structural health monitoring (SHM) of long-span tracks. In order to ensure the safe operation …

The 2: 1 internal resonance of electrostatically coupled resonators is theoretically
investigated. A general dynamical model of the coupled resonators is established, and a …

Nonlinearly coupled vibrations in microelectromechanical sensors have received much
attention for their great potential in improving sensor performance. In this paper, a novel …

The wireless energy transmission technology is utilized in the integrated primer fuze device
to achieve the integrated transmission of energy and information for weapon equipment. A …

Cette thèse porte sur la conception de récupérateurs d'énergie vibratoire. Il s' agit de
dispositifs peu encombrants capables de convertir l'énergie des vibrations en électricité afin …
