Abstract

Traditionally, fast Fourier transform (FFT) is used to analyse stationary time series in fluid mechanics research. This approach is inadequate when FFT is used to examine time series obtained from fluid/structure interaction studies. The reason is the difficulty of extracting damping information from a FFT analysis. This information is important to vibration studies. The present investigation proposed to used an approach based on the autho-regressive moving analysing (ARMA) identification technique to analyse the time series obtained from a numerical simulation of a uniform cross-flow past an elastic cylinder. Damping characteristics of the fluid/structure system as well as its natural frequencies for a number of elastic cylinders are examined. The results are very encouraging, even though experimental measurements are not available for verification.
