An Analysison Electrical Properties of Ship Structure Based on the Mechanism of Shaft-rate Electric Field

舰船轴频电场日益成为舰船的重要目标特性,易被对方探测、跟踪、定位和打击,在分析舰船电场电能来源的基础上,研究了舰船轴频电场的影响因素,分析舰船主要结构,建立其电学等效电路模型,变换、简化等效电路并进行分析,得出了电学特性。研究结果表明,轴系变化阻抗是舰船轴频电场的主要影响因素,电学特性分析是舰船轴频电场抑制技术的研究基础。

Shaft-rate electric field of the ship is becoming an important target characteristic,for it is easily detected,tracked,located and attacked by the opposite side. On the basis of an analysis on the source of electric power of the ship electric field,this paper discusses the factors affecting the ship shaft-rate electric field,analyzes the main structure of the ship,establishes an electrical equivalent circuit,converses and simplifies the equivalent circuit,and obtains its electrical properties. The research results show that the shafting variance impedance is a major factor affecting the ship shaft-rate electric field,and the analysis of its electrical properties is the basis for research of the technology suppressing the ship shaft-rate electric field.
