摘要
轴频电场是由螺旋桨转动时因主轴和轴承之间的接触阻抗不恒定而导致流经主轴的腐蚀或防腐电流受到周期性调制而产生的,是舰船的一个重要目标特征信号。在研究轴频电场等效电流回路中发现,轴系部件电阻的变化是影响轴频电场的重要原因。本文通过对舰船实体结构简化分析,得到等效电路中主要轴系电阻部件,并进一步对影响轴系部件电阻波动因素进行分析。
Shaft-rate electric field is produced by shaft current modulated by shaft rotation caused by impedance changes between shaft and bearing. Shaft-rate electric field is one of the important target characteristic signatures of shipping. In the study of equivalent circuit of Shaft-rate electric field, impedance changes between shaft and shaft component is an important reason. The paper, analyzes entity structure of the ship and points out the main impedance components, and further analyzes the influence factors on the resistance fluctuation in shafting parts.
