  • 摘要: 利用MOSES计算软件,运用三维势流理论建立起重船系泊状态下的吊重作业计算模型,计算吊重与船的六个自由度的运动,对吊重绕吊臂吊点的摆动进行研究,分析船舶系统的运动特性。在时域计算中,引入风浪流海洋环境条件,使计算条件更加符合工程实际。以一艘起重船为例,选取船体重心和吊物质心为关键点,改变系泊缆预张力,使缆绳张力控制在安全范围内。通过改变起吊要素,分析这些要素对吊重运动及船体运动的影响,以及吊重摆动与船体横摇运动的相互影响。
    Abstract: This paper establishes the computational model of hoisting operation in mooring floating cranes,based on the 3-D potential flow theory and the MOSES computing software. In particular,the movements of the hanging object and the crane are analyzed on six degrees of freedom,the swing motion of the hanging object around the boom point is investigated,and the kinetic characteristic of the ship is then presented. Also,when performing the calculation in the time domain,the model incorporates several marine parameters such as wind,waves and flow to make the result more accordant with engineering practice. To validate the proposed model,a particular floating crane is examined in experiments. The Center of Gravity(CG)of the hull and the center of the hanging object are first defined as two key points,and the tension on the mooring cable is correspondingly adjusted within a safe range. By gradually changing the hoisting condition,the movement of the hull and the hanging object can be analyzed,and the relationship between the rolling of the crane and swing of the object is revealed.
