摘要
预测和计算水下垂直拖曳线列阵的水下受力构型是拖曳线列阵设计中的重要环节。论文通过对测量船尾部悬挂的水下垂直拖曳线列阵进行受力分析,建立仿真模型,计算多种工况条件下拖曳线列阵角度偏移和阵列受力情况。仿真结果表明:角度偏移、拖曳力随速度的增加而增大,速度变化斜率随锚体质量的增加而增大;垂直拖曳线列阵长度与角度、拖曳力呈正比关系,且低速条件下阵列长度变化对角度影响大。为避免对系统带来安全隐患,相对速度应控制在4m/s以内,拖曳线列阵长度应控制在100m以内。
Predicting and calculating the underwater force configuration of the underwater vertical tow line array is an impor tant part of the design of the towed line array.In this paper,the force analysis of the underwater vertical line array suspended in the measuring stern is carried out,and the simulation model is established to calculate the angular displacement of the tow line array and the force of the array under various working conditions.The surface of the simulation results show that the angular offset and the drag force increase with the increase of the speed,and the speed change efficiency increases with the increase of the mass of the an chor body,the length of the vertical tow line array is proportional to the angle and the drag force,and the array is under low speed conditions.The length change has a large influence on the angle.In order to avoid safety hazards to the system,the relative speed should be controlled within 4m/s,and the length of the towed line array should be controlled within 100m.
