Contributions on the Problem of Ship Vibration.
Abstract
Contributions to three problems of ship vibrations, (a) added masses of two-dimensional ship sections (including horizontal vibrations at a free surface), (b) three-dimensional corrections to strip theory, and (c) three-dimensional theory for vibration in a liquid, presented in a series of 16 papers, are briefly summarized. If strip theory is used, it is preferable to determine the added mass of a ship section by conformal mapping than by matching against families of forms of known added mass. If natural frequencies at higher modes are required, the three-dimensional vibration theory, which essentially replaces the added-mass vector of strip theory by an added-mass matrix, should be employed.
