舰船物理场半实物仿真实验平台开发

Design of Hardware in the Loop Simulation Experimental Platform of Ship’s Physical Fields

该文针对舰船物理场海上测量实验经费耗费巨大且难于组织实施的问题,设计了舰船物理场半实物仿真实验平台。通过舰船物理场数学模型,模拟在不同航向和方位角情况下各类目标舰船通过时的物理场,采用声、磁和水压传感器感知物理场。实践表明,借助该实验平台,在实验室条件下就可以观测到舰船通过时的声场、磁场和水压场信号波形,并可通过测量存储的数据分析信号的时域和频域特征。

Aiming at the problem that the maritime measurement experiment of the ship physics field is costly and difficult to or⁃ganize,a hardware-in-the-loop simulation experiment platform of ship’s physical fields is designed.Through the mathematical model of the ship physics field,the physics field of various types of target ships passing under different heading and azimuth angles is simulated,and the physics field is sensed by acoustic,magnetic and water pressure sensors.Practice shows that with the experimental platform,the sound field,magnetic field and water pressure field signal waveforms of the ship passing through can be observed under lab⁃oratory conditions,and the time domainand frequency domain characteristics of the signal can be analyzed by measuring the stored data.
