Bending wave bandgap control of a local resonant pipe with a honeycomb thin-wall structure

Abstract The reduction of low-frequency vibrations in marine vessels has become an important research direction due to their impact on ship performance and comfort. This study addresses vibration issues in ship pipeline systems by proposing a novel honeycomb thin-walled (HTW) vibration damper, aimed at extending the bandgap in the low-frequency range and improving vibration attenuation. Unlike traditional locally resonant photonic crystals (LRPCs), the HTW structure offers enhanced performance by overcoming the limitations of narrow bandgaps and high-frequency operation. A finite element model was constructed for further band structure analysis. Compared to existing technologies, the HTW damper provides new design insights and technical references for low-frequency vibration control, with broad potential applications. In conclusion, this research provides an innovative solution for low-frequency vibration control in marine vessels and related fields, opening new avenues for further research and technological development in this area.
