多线圈作为超磁致伸缩换能器内部的重要组成结构，其在工作状态下因涡流效应所引起的电阻损耗是不可忽视的。而单芯、多芯线圈的涡流损耗作用机理并不相同，单芯线圈电阻损耗主要由趋肤效应主导，多芯线圈的电阻损耗则是由趋肤效应及邻近效应共同影响。该文基于麦克斯韦方程组和涡流效应推导出单芯、多芯线圈电阻损耗的解析计算式，并使用有限元方法对通以相同电流、相同横截面积情况下的单芯、多芯线圈进行不同超声频段下的损耗研究，最后基于RLC串联电路谐振状态下电路呈纯阻性的原理，测量单、多芯线圈的交流电阻，结合损耗功率计算公式进而得到线圈的涡流损耗。实验结果与仿真模拟结果、解析计算结果相吻合，验证了线圈功率损耗解析计算式及实验方法的有效性。
Abstract：As an important internal structure of a super magnetostrictive transducer, the resistance loss caused by the eddy current effect in the working state of multi-coil cannot be ignored. The mechanism of eddy current loss of single-core and multi-core coils is not the same. The resistance loss of single-core coils is mainly dominated by the skin effect, while the resistance loss of multi-core coils is influenced by both the skin effect and the proximity effect. In this paper, based on Maxwell's equations and eddy current effect, the analytical calculation formula of the resistance loss of single-core and multi-core coils is derived, and the finite element method is used to study the loss of single-core and multi-core coils under different ultrasonic frequency bands under the same current and the same cross-sectional area, and finally based on the principle of pure resistance of the circuit in the resonant state of RLC series circuit, the AC resistance of single-core and multi-core coils is measured, and the eddy current loss of the coil is obtained by combining the calculation formula of the loss power. The experimental results are consistent with the simulation results and analytical calculation results, verifying the effectiveness of the analytical calculation formula and experimental method for coil power loss.
