Vibrations of streamlined perforated plate

Abstract

Object and purpose of research. A study of inception conditions for hydroelastic self-induced vibrations of perfo-rated plate in slip flow. Materials and methods. Vibration spectra measurements of plate in flow. Analysis of physical nature of vibration fre-quency spectra maximums. Main results. Inception conditions for hydroelastic self-induced vibrations of perforated plate in slip flow were determined. Conclusion. Proposals for prevention the inception of hydroelastic self-induced vibrations in ship structures including per-forated plates in water slip flow were formulated.
