摘　　要：文章应用数值水池技术针对耙吸挖泥船带水下泵耙管结构的拖曳阻力特性在实尺度下进行虚拟试验,分析研究裸耙管和全附体耙管随下放角度、航速变化的拖曳阻力特性及全附体耙管各组成结构的阻力分量情况,为耙吸挖泥船耙管的拖曳阻力预报、船舶推进功率评估、耙管结构设计优化提供参考。A virtual experimental study of the resistance characteristics of the suction pipe structure of a full-scale trailing suction dredger with the underwater pump has been carried out by using the numerical tank technology.It analyzes and studies the resistance characteristics of the bare and fully appended suction pipe that are varied with different inclined angles and speeds.It also analyzes the resistance components of each structure of the fully appended suction pipe.It can provide reference for the resistance prediction,evaluation of the ship propulsion power and the design optimization of the suction pipe structure.
