摘要

以四角架筒型基础为研究对象,通过在静水及规则波作用下的模型试验对影响结构气浮过程中运动特性的因素进行分析。结果表明,结构摇荡运动的附加质量系数随吃水的增加呈下降趋势,都大于船舶动力学的建议值1.2;随着吃水的增加,垂荡运动呈先减小后增大的趋势,而纵摇运动呈减小的趋势;较浅水深增强了结构的竖向运动,垂荡和纵摇运动的最大幅值随水深的变化呈相反的变化趋势;四角架筒型基础结构在4.5 m吃水和12.5 m水深下的运动响应特性最佳。

Abstract

Taking a tetrapod bucket foundation as the research object, the factors influencing the motion characteristics of the structure during air-floating are investigated by model tests in still water and regular waves. The results indicate that the added mass coefficient of oscillating motion decreases with the increase of draft, which is greater than the recommended value 1.2 in ship dynamics. As the draft increases, the heaving motion first decreases and then increases, while the pitching motion decreases. The vertical motions of the structure are enhanced in shallower water. However, the change trend of maximum amplitude of heaving motion is opposite to that of pitching motion with the change of water depth. The optimal motion responses of the structure are achieved at 4.5 m draft and 12.5 m water depth.
