Abstract

In this study, an experimental investigation is presented on transverse vibrations of a highly flexible free hanging pipe in water by top end oscillations. The natural frequencies of the model are obtained by theoretical and experimental methods. The largest response amplitude of transverse vibrations occurs at the bottom part of the model for all excitation frequencies and amplitudes. Transverse structural wave propagation is observed at the experiment and found in the measured data analysis. A transverse structural wave initiated at a particular point by vortex shedding propagates along the model length and results in all the same frequency of transverse vibrations along the model. Structural wave propagation plays an important role in the vortex induced transverse vibrations of slender marine structures.
