摘要
为降低舰船腐蚀相关电场信号,分析电流补偿方法对轴频电场信号和主动轴接地(ASG)技术对静电场的影响,基于电流补偿与ASG之间的关系,提出轴频与静电场一体化的电场隐身控制方法。把ASG系统的补偿电流值视为船体的轴电流值,并将电流补偿方法中补偿电流与轴电流之间的比值κ作为电流控制量,实现了先轴频电场隐身、后静电场隐身;研制轴频电场与静电场一体化电场隐身控制原理样机,通过模型试验和海上试验结果对轴频电场与静电场一体化控制方法的性能进行检验。结果表明:该方法能够有效降低静电场与轴频电场信号。
To decrease the ship's corrosion-related electric field,the effects of the current compensation technology on shaft-rate electric field and the active shaft ground technology(ASG)on the static electric field are analyzed,respectively.An integration method of decreasing both static electric field and shaft-rate electric field is proposed based on the correlation between current compensation and active shaft ground.In the proposed method,the compensation ASG current is regarded as the shaft current,and the ratio between compensation current and shaft current is used as the controlling parameter of current compensation,thus realizing the stealth of shaft-rate electric field firstly and then that of static electric field.Finally,a prototype of this new method is developed,and its effectiveness is examined by ship model experiment and sea trial,respectively.The results show that the proposed method is effective in decreasing both static electric field and shaft-rate electric field.
