摘　　要：针对低频强磁场模拟试验设备中的磁场发生线圈为一大型疏绕螺线圈组,其电感系数难以利用现有公式计算的实际问题,采用理论公式计算该螺线圈组的自感,采用ANSYS有限元仿真计算其有效电感系数(包括自感和互感)。同时,将数值计算结果与实体螺线圈有效电感的测试数据进行了对比分析。研究结果已应用于低频强磁场模拟试验室磁场发生线圈的设计和其电阻、电器、电容脉冲电流激励电路参数的确定。The magnetic field generating coil of the low-frequency magnetic field simulation device is a large sparse solenoid,its self-inductance and mutual inductance cannot be calculated by using the familiar formulas.In order to solve this problem,theoretical formulas were used to calculate the self-inductance of the solenoid,and ANSYS finite element simulation was used to compute its effective inductance( including self-inductance and mutual inductance). The testing data of the low-frequency high magnetic field generating coil were analyzed simultaneously. The results of this paper have been used to design the magnetic field generating coil of low frequency high magnetic field generating laboratory,and to determine the circuit parameters of resistorinductor-capacitor pulsed current excitation.
