摘要
为了进一步提升深海阵列式拖曳系统的深度调节性能,满足阵列式拖曳系统不同深度作业的需求,设计了一种通过内部调节机构来改变运动姿态与深度变化的水下拖曳体,并对这一水下拖曳体的水动力学进行数值计算。在研究其水动力学相关参数基础上,分析水下拖曳体重心位置变化与运动姿态的关系,验证内部调节机构的可行性。仿真结果表明,拖曳体的设计满足使用要求,不同俯仰角下水下拖曳体深度变化的时间有所不同。在俯仰角40°左右范围内,拖曳体的升力系数最大,并呈现较好的深度调节运动姿态。
In order to further improve the depth adjustment performance of abysmal sea array towing system, and to meet the requirements of array towing system in different depth operations, one underwater towed vehicle is designed which changes motion attitude and depth through an internal adjusting mechanism, and carries out the hydrodynamic numerical calculation of the underwater towed vehicle. Based on the studies of the related parameters of hydrodynamics, the paper analyzes the relationship between gravity position change and motion attitude of the underwater towed vehicle, and verifies the feasibility of the internal adjusting mechanism. The simulation results show that the design of the towed vehicle meets the application requirements. As the depth changes, the underwater towed vehicle costs different time at different pitching angles. In the pitching angle range of around 40°, the underwater towed vehicle has the maximal lift coefficient, and presents a better depth adjustment motion attitude.
