Abstract
If the free liquid surface in a circular cylindrical container is partially covered by a structural element, the natural frequencies of the liquid are exhibiting increased magnitude. In addition, a much calmer liquid motion results from such coverages. In order to save structural weight, such devices may exhibit elastic behavior. The following investigation treats the hydroelastic problem of the interaction of liquid sloshing with an elastic annular plate structure attached to the cylindrical sidewall. It was found that decreasing rigidity of the annular plate exhibits less increase of the natural frequencies than that of a rigid plate. The increase of the plate width and a decrease of the Bond number increases the natural frequency drastically.
