8000kW救助船规则波下的运动与波浪载荷预报

Motion Performance and Wave Load Prediction for a 8000 kW Rescue Vessel under Regular Wave

随着数值计算技术的发展,船舶运动与波浪载荷预报精度也在不断提高。介绍了三维势流理论方法在规则波上船舶运动与波浪载荷预报中的应用,以8 000 k W救助船为例,预报了其运动与波浪载荷。通过应用三维势流理论,可以为船舶耐波性评估和结构设计提供依据。

With the development of numerical calculation, the method on prediction of ship motion and wave load had been improved continuously. This article introduced 3D potential flow method applied on ship motion and wave load prediction. An 8 000 kW rescue ship was taken as an example to demonstrate the process of predicting ship motion and wave load. 3D potential flow method could be used to evaluate ship seakeeping performance and to serve as reference for structure design.
