摘　　要：针对舰艇回转测噪中的操纵模式设计方法效率低下的问题,提出一种基于拖线阵稳态特性和舰艇旋回特性的操纵模式设计方法。通过调整法向阻力系数,使零浮力缆稳态振荡响应公式适用于阵流夹角较大的情况,并将其拓展应用于拖点回转运动的场景;利用等效代换原则建立拖线阵稳态振荡响应模型;定义回转测噪理想阵位,提出各车钟条件下满足测噪要求的回转半径区间的计算方法,进而依据舰艇旋回特性得到相应舵角区间。仿真结果表明,所提出的方法能够较高效地实现操纵模式设计,可以满足实际工程的应用要求。In order to solve the inefficiency of steering mode design in ship noise measurement using its own towed array,a method of steering mode design based on steady-state characteristics of towed array and ship's rotation characteristics is proposed.By adjusting the normal drag coefficient,the steady-state vibration response formula of neutrally buoyant array is applied to the case where the cable/array angle is large,and it is extended to the scene of circular maneuvering.Steady-state vibration response model of towed array is established by using equivalent substitution principle.The ideal relative position of the noise measurement by circular maneuver is defined.The method to get the radius interval of circular maneuver is proposed,and then the corresponding steering gear interval is obtained according to the ship's rotation characteristics.The simulation results show that the proposed method can design the steering mode more efficiently and can meet the requirements of engineering application.
