摘要
研究发现,舰船主要轴系部件具有很高的结构相似性且都存在周期性变化的接触电阻。经过对舰船结构的实体调研和轴系结构的简化,建立了轴系部件接触电阻物理模型,并进行理论分析和实验验证。结果证明:接触电阻变化导致回路中电流的波动,变化率可达80%,是产生轴频电场的一个重要因素。
The study found that a high structural similarity and periodic contact resistance existed in the main shaft parts of ship.Physical contact resistance of shaft parts is established after researched and sim-plified the structure of the entity ship structure,and then have theoretical analysis and experimental verifi-cation to the model.The results prove that the contact resistance variation lead to fluctuations in the loop current,the change rate is up to 80%,which is an important factor in generating shaft-frequency electric field.
