| 摘 要： | 文章用数值仿真法研究了船舶结构搁浅中的内部力学问题,分析了典型双层底结构的损伤变形、受力和能量耗散结果。研究表明,损伤变形集中于搁浅的区域,搁浅力学问题主要考虑局部的船体结构;肋板的存在显著地增加船底结构的抗搁浅能力,使礁石的垂向贯入量会略有减小;当纵桁远离搁浅区域时,它的吸能能力无法发挥,抗搁浅作用明显削弱。

| Abstract: | The paper presents a study on internal mechanism of ship grounding in the way of numerical(simulation) and the results of damage deformation,contact forces and energy dissipation.The study shows the damage deformation occurs mainly at the grounding area,so the grounding mechanism shall focus mainly on the local structure of the ship.It is revealed that the existence of floors remarkably increases the grounding-resistance ability of bottom structure by moderating the vertical penetration of the rock into the hull structure.It is proved when the longitudinal girder is far sway from the grounding area,it fails to play its energy absorption ability and fails to show its grounding-resistance effect. |
