Advanced Ship VIbration Modelling for Large Passenger Ships for Safety and Comfort

近年来，随着结构变得更轻，确定船舶振动特性的需要在船舶设计过程中具有更高的优先级，这是因为，首先，许多船舶由于动态应力引起的疲劳损坏而遭受结构失效，其次，过度振动通常导致船舶设备的损坏或故障，第三，经受过度振动的船舶人员由于疲劳而经历不适和他们执行任务的熟练度。然而，振动是否被判断为过度取决于所应用的标准，即疲劳损伤、不适或一些其他故障。本项目将详细研究各种问题的适当限度。

The need to establish the vibration characteristics of a ship has, in recent years, assumed a greater priority in the ship design procedure as structures have become lighter because, firstly, a number of ships have suffered structural failure due to fatigue damage resulting from dynamic stresses, secondly, excessive vibration commonly results in damage to, or malfunction of, ships' equipment and, thirdly, ships' personnel subjected to excessive vibration experience discomfort and their proficiency in carrying out tasks due to fatigue. However, whether or not vibration is judged to be excessive depends upon the criterion to be applied, that is, fatigue damage, discomfort or some other malfunction. Appropriate limits for the various problems will be investigated in detail in this project.
