摘要
为考虑拖体姿态对其入水深度和拖缆干端拉力影响,通过理论计算与流体力学仿真相结合方式,对不同航速下拖体拖曳稳态纵倾角及拖体所受水动力进行计算,并以计算结果为边界条件,依据拖曳系统计算理论编程计算拖体入水深度及拖缆干端拉力。将其与不考虑拖体姿态随航速变化因素的计算结果相比,结果显示该结果与试验数据更为接近。
In order to consider the influence of the attitude of the towing body on its water entry depth and the pull force at the main end of the towing cable,the steady-state trim angle of the towing body and the hydrodynamic force on the towing body under different speeds are calculated through the combination of theoretical calculation and hydrodynamic simulation.Taking the calculation results as the boundary conditions,the water entry depth of the towing body and the pull force at the main end of the towing cable are programmed according to the calculation theory of the towing system,Compared with the calculation results without considering the change of towed body attitude with speed,it is closer to the experimental data.
