摘　　要：海洋地处国防前哨,是维护国家安全的重要屏障,也是我国实施“一带一路”倡议的重要载体。超低频声波是唯一可以在水下远距离传播信息的载体,这使得大功率超低频声波发射装备逐渐成为海洋工程与研究的关键。电磁换能器具有结构原理简单、输出力大、成本低、易组成换能器阵列的优点,是实现大功率超低频发射的有效方式之一。目前,欧美发达国家已对大功率超低频电磁换能器进行了大量的理论和技术研究,并取得了一定的研究进展;国内该领域仍处于起步探索阶段,讨论了国内外大功率超低频电磁换能器的发展现状,分析了装备研制的关键技术,并对未来大功率超低频电磁换能器发展趋势和应用进行了展望。Located in the outpost of national defense,the ocean is an important barrier to safeguard national security and an important carrier for China to implement the“Belt and Road”Initiative.Ultra-low frequency(ULF)sound wave is the only information carrier that can propagate long distance underwater,which makes high-power ULF sound wave transmitting equipment gradually become the key of ocean engineering and research.Electromagnetic transducer has the advantages of simple structure principle,large output force,low cost and easy formation of transducer array.It is one of the effective ways to realize high-power ultra-low frequency emission.At present,developed countries in Europe and the United States have carried out a lot of theoretical and technical research on high-power ultra-low frequency electromagnetic transducers,and have made certain research progress,but the domestic research in this field is still in the initial stage.In this paper,the development status of high-power ultra-low frequency electromagnetic transducers at home and abroad is discussed,the key technologies of equipment development are analyzed,and the development trend and application of high-power ULF electromagnetic transducers in the future are prospected.
