摘要
绞吸挖泥船在作业过程中受到载荷影响的情况较为复杂。以某绞吸挖泥船为研究对象,采用计算流体动力学(Computational Fluid Dynamics,CFD)数值模拟模型对绞吸挖泥船风流载荷进行分析,得到无因次的风流载荷系数,总结绞吸挖泥船风流载荷规律。研究结果可为绞吸挖泥船的系泊分析和作业过程安全性分析提供一定参考。
The situation that the cutter suction dredger is influenced in the operation process by the loads is complicated.Taken a cutter suction dredger as the research object,the wind load and current load of cutter suction dredger are analyzed with the numerical simulation model of Computational Fluid Dynamics(CFD),the dimensionless coefficients of wind load and current load are obtained,and the law of wind load and current load of cutter suction dredger is summarized.The research results can provide certain reference for mooring analysis and operation process security analysis of cutter suction dredger.
