dc.description.abstract Hydrodynamic influence on ship’s hull vibration in water is expressed in terms of added mass, which depends on flow domain, such as water depth, flow-field boundaries, ship’s underwater shape and vibration modes. The problem of the added mass of a uniform ship-hull girder vibrating vertically in deep water and close to water bottom is studied. Numerical values show that the effects of shallow water are significant and quite important in ship’s hull vibrations. en_US
dc.description.abstract Influenţa hidrodinamică asupra vibraţiilor corpului navei în apă este exprimată în termeni de mase adiţionale, care depind de domeniul de curgere, cum ar fi adâncimea apei, frontierele domeniului, forma imersă a navei şi modurile de vibrare. Este studiată problema maselor adiţionale a corpului navei văzut ca o grindă uniformă, care vibrează vertical în apă adâncă şi totodată în ape mici. Valorile numerice obţinute arată că efectul apelor mici este important în studiul vibraţiilor corpului navei. ro
dc.description.abstract L'influence hydrodynamique sur la vibration de la coque du bateau dans l'eau est exprimée en termes de masse supplémentaire, qui dépend du domaine d'écoulement, tel que la profondeur de l'eau, frontières de couler-champ, forme sous-marine du bateau et modes de vibration. Le problème de la masse supplémentaire d'une coque vu comme poutre uniforme vibrant verticalement dans l'eau profonde et près du fond de l'eau est étudié. Les valeurs numériques prouvent que les effets de l'eau peu profonde sont significatifs et tout à fait importants dans les vibrations de la coque du bateau. fr
dc.description.abstract Гидродинамическое влияние на вибрацию судна в воде выражено в виде добавочных масс, которые зависят от области течения, глубины воды, границы области, форма корпуса судна и вида вибраций. Исследована проблема добавочных масс корпуса судна рассматриваемого как равномерная балка, которая вибрирует вертикально в глубокой и одновременно неглубокой вод. Полученные численные результаты показывают что эффект малых вод важен при исследовании вибраций корпуса судна. ru
