摘要：
The statistical properties of the second-order Froude-Krylov force on a cylinder (whether a vertical cylinder or a horizontal submerged cylinder), for narrow-band spectra, are investigated. Two families of stochastic processes are defined for this purpose, and for each family the probability density function and the, probabilities of exceedance of the absolute maximum and of the absolute minimum are obtained. It is then proven that the above-mentioned Froude-Krylov force processes belong to these stochastic families. The predictions for the Froude-Krylov force on a horizontal submerged cylinder agree with the results of a small-scale field experiment.
