A Study on Slamming Impact Load Characteristics of Energy Storage System Case for Ships

As part of the environmentally friendly policy ships, active research is being conducted on energy storage systems (ESS) for ships. This ESS has a major influence determining propulsion and operation system ship in future. A separate space must be provided ESS, but small medium-sized ships often require it to located at bottom make use available space. If ship, slamming impact load should considered, study vibrations generated during required. Ships are subjected various environmental effects while sailing. Among them, risk factor caused by waves one direct factors ship. phenomenon affects not only also offshore structures, that can cause structural damage as well human life. Therefore, necessary load, method needed address with dynamic instead static load. In order reflect design rather than equivalent hydrostatic pressure, which elastic effect structure. The plate thickness calculated considering pressure based measured peak, several experimental theoretical studies have been estimate exact value peak pressure. However, according recent studies, affected width time interval Research ongoing long time, due still reported steadily. understand formula, high-quality results occurs very short time. obtain this phenomenon, numerous variables such equipment setting, appropriate sensor selection, data measurement capability carefully considered. Normally expressed terms width, duration maximum idealized (impulse) applied shape natural period structure shows largest when dead-rise angle 3° 10°. study, test was performed repeatedly dropping into water using angles 0°, 3°, 10°, 20° free surface water. impulse, coefficient, traveling velocity obtained from repeated tests estimated mean coefficient variation.
