大型自卸船船体振动研究

Study on the vibration of large self-unloading ship

近年来 ,由于船体产生有害振动而导致延误交船事件时有发生 ,因此振动的予报已放到船舶设计部门的议事日程上来。本文着重介绍了大型自卸船在不同的设计阶段的船体振动予报与控制 ,评判标准是采用 ISO6 95 4的标准 。

Recent years have seen a number of cases of new-building delivery delay due to harmful hull vibration. So ship designers began to study how to forecast this vibration. This paper presented the way how to do vibration forecast and control at each design stage for large self-unloading. The judging standard is based on ISO 6954. It is believed the conclusion presented in the paper may benefit the design of this type of ship in the future.
