摘要

摘要: 基于舰船尾流基本理论知识研究了尾流的波形、速度和感应磁场的分布, 得到了舰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。求解了多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、快速的模拟设定三艘船型尾流在任意方向的磁感应强度的大小和变化规律, 而且具有操作简便、节省成本的优势, 为船舶尾流实验和探索海洋资源提供了更好的基础和有效的仿真平台。

Abstract: Based on the basic theoretical knowledge of ship wake, the waveform, velocity, and distribution of induced magnetic field of the wake were studied, and the variation characteristics and distribution patterns of the induced magnetic field in the ship's stern were obtained. Taking the formation of three ships as an example, the distribution of induced magnetic field and the distribution of magnetic field in the direction of x、y during the movement of the ships were analyzed. The magnetic field distribution characteristics of the tail flu formed when multiple ships sail at the same time were solved, and analyzed the abnormal induced magnetic field generated during various ship combination operations. The experimental results obtained from the simulation are consistent with the existing measurement results.Using APP Design tools for ship wake magnetic anomaly simulation system software development, the system can not only accurate, intuitive, fast simulation set three ship type wake in any direction of magnetic induction strength and change law, and has the advantage of simple operation, cost saving, for the ship wake experiment and explore Marine resources provides a better foundation and effective simulation platform.
