船舶与系泊平台模型碰撞试验研究

Experimental Study on Collision Between Ship and Mooring Platform Model

文中搭建了能够模拟船舶与系泊平台碰撞的模型试验平台,并在试验水池中开展了四组典型工况下的模型碰撞试验,研究了船舶碰撞载荷下系泊平台的动力响应问题.分析了不同碰撞速度以及系泊线预张力对碰撞过程中碰撞力、系泊线张力,以及被撞平台运动响应的影响,讨论了试验中系泊平台的横摇、纵摇及首摇的变化趋势,探讨了被撞平台外板的变形损伤情况.结果表明:碰撞过程中的最大碰撞力和前端及后端系泊线最大张力平均值与碰撞速度近似呈线性增长关系,系泊线预张力对最大碰撞力及系泊线最大张力也有一定的影响.系泊平台的变形损伤较小,撞击船的大部分能量都转化成了系泊平台的动能.

A model test platform which can simulate the collision between ship and mooring platform was built.The model collision tests under four typical working conditions were carried out in the test pool,and the dynamic response of the mooring platform under ship collision load was studied.The effects of different collision speeds and mooring line pre-tension on collision force,mooring line tension and the motion response of the hit platform were analyzed.The changing trends of the rolling,pitching and pitching of the hit platform in the test were discussed,and the deformation and damage of the outer plate of the hit platform were analyzed.The results show that the maximum collision force and the average of the maximum tension of the front and rear mooring lines in the collision process increase linearly with the collision speed,and the pre-tension of the mooring lines also has some influence on the maximum collision force and the maximum tension of the mooring lines.The deformation damage of the mooring platform is small,and most of the energy of the collision ship is converted into the kinetic energy of the mooring platform.
