摘要

摘要: 为研究多艘舰船同时航行时尾流磁异常特性, 基于舰船尾流基本理论知识研究了舰船尾流的波形、速度以及感应磁场的分布, 得到了多船尾流感应磁场的变化特性和分布规律。以3艘舰船编队为例, 分析了舰船在运动过程中感应磁场分布及在 x、y方向上的磁场分布情况, 求解了3艘船同时航行时形成的尾流感应磁场分布特性, 并对各种舰船组合航行时产生的感应磁场异常情况进行分析。仿真所得实验结果符合现有测量结果。利用APP Design工具对多舰船尾迹磁异常特性进行仿真系统软件的开发, 该系统不仅能够准确、直观、快速地模拟设定3艘船型尾流在任意方向的磁感应强度大小和变化规律, 而且具有操作简便、节省成本的优势, 为舰船尾流实验提供了理论参考和更为有效的仿真平台。

Abstract: In order to study the characteristics of the wake magnetic anomaly when multiple ships are sailing at the same time, based on the basic theoretical knowledge of ship wake, the waveform, velocity, and distribution of the induced magnetic field of the ship wake were studied, and the variation characteristics and distribution patterns of the induced magnetic field of the multi-ship wake were obtained. By taking the formation of three ships as an example, the distribution of the induced magnetic field and the distribution of the magnetic field in the directions of x and y during the movement of the ships were analyzed. The magnetic field distribution characteristics of the wake formed when the three ships sail at the same time were solved, and the abnormal induced magnetic field generated during various ship combination operations was analyzed. The experimental results obtained from the simulation were consistent with the existing measurement results. APP Design tools were used for magnetic anomaly simulation system software development of multi-ship wake. The system not only could accurately, intuitively, and quickly simulate and set the magnetic induction intensity and variation patterns of the wake of three ships in any direction but also had the advantages of simple operation and cost saving, which provided a theoretical reference and a more effective simulation platform for ship wake experiment.
