报告摘要:

砰击是船体结构与波浪相互作用而产生的一种剧烈流固耦合现象。船舶在恶劣海况中航行时会产生六自由度摇荡运动,当船首露出水面后再次入水的过程中,会与水面发生高速撞击从而产生砰击载荷。巨大的冲击载荷会引起船体结构振动和局部结构损伤与破坏。因此,准确预报船体砰击载荷对于船体结构的设计与安全评估至关重要。

本报告将围绕局部砰击现象开展介绍,主要包括三个方面内容:砰击现象出现的情况和发生概率、砰击载荷的预测方法和砰击引起的结构响应。首先,以一艘化学品船为例,介绍预测船舶砰击事件的发生概率及载荷的数值方法。然后介绍基于任意拉格朗日-欧拉方法和解析方法预报船体剖面砰击载荷的理论与数值模拟方法。此外,还将给出典型结构物在砰击载荷作用下的结构动力和水弹性响应的解析解。最后,对采用数值和试验方法预报砰击载荷中的不确定性问题的研究进展进行综述。

 

Hull slamming is a phenomenon that occurs when the ship hulls come out of the water due to the relative vertical motions between the vessel and the water surface and then enters the water surface with a relatively high speed. The generated impulsive forces may induce considerable vibrations and local structural damages. Thus the accurate prediction of hydrodynamic slamming forces acting on ship hull structures is crucial in the design of marine structures.

The report will introduce three main research aspects regarding the local slamming phenomenon: where and how often a slam event occurs; slamming load prediction methods, and structural responses due to slamming loads. Firstly, a numerical method for predicting the slamming probability of occurrence and loads of ships will be presented with an example of a chemical tanker. Then the assessment of slamming loads on ship sections using arbitrary Lagrange-Eulerian method and analytical models will be discussed. In addition, the analytical solutions for determining the dynamic or hydroelastic responses of simple ship structures subjected to slamming loads will be presented. Furthermore, the recent research progress regarding the numerical and experimental uncertainty on slamming loads assessment will be reported.
