摘    要:舰船水下电场信号作为重要的物理特性已受到广泛的关注和研究。通过研制船模并进行水下电场实验室测量来了解实船水下电场分布情况,可以较好地解决舰船水下电场的海上测量较困难这一问题。通过引入相似性原理,分析比例船模的电场分布与实船电场分布的相似性关系,提出满足相似性的电场船模设计准则,实船和船模水下电场对比实验验证了相似性准则的有效性。

关 键 词:船模  实船  水下电场  相似性

Abstract:The Underwater Electric Field (UEF) of naval ships has always been a focused topic due to its critical physical characteristics. However, it is often quite difficult to measure the UEF of naval ships during sea trial. To solve the problem, the UEF of a physically scaled model ship is first studied and then compared with the field data in light of the similarity theory. The resuh successfully validates the similarity principle, which indicates that the UEF of a real naval ship can be obtained by measuring the data from a scaled ship model. This research may provide valuable references for the electric field forecasting during the ship design process.
Keywords:scaled model ship  actual naval ship  Underwater Electric Field(UEF)  similarity theory
