摘　　要：在船载无人艇收放技术中,拖体吊笼具有使用简单,回收效率高的特点。论文以某拖体吊笼模型为研究对象,对其在静水和波浪条件下拖航运动的姿态进行数值模拟,研究拖缆角度对拖体吊笼运动的影响。开展了相关的模型试验,并将仿真结果与试验数据进行比较。研究结果表明,拖曳角对拖体吊笼的姿态有较大的影响,在波浪环境中其影响尤为显著。In technologies of releasing and recovering unmanned surface vessels,towing cage has characteristics of simple use and high efficiency of recovery.In this paper,a towing cage model is used as the calculation object,and its attitude in towing motion under static water and waves conditions is calculated.The uncertainty of the grid size and time step of the calculation model is analyzed,and influence of the towing angle of the cable on the motion of the towing cage is studied.Relevant model tests are carried out,and the simulation results are compared with the experimental results.The results show that the towing angle of the cable has great influence on the attitude response of the towing cage,especially under wave conditions.
