摘　　要：传统旋转式可调电感设计方法通过实物迭代进行制作,时效性和经济性较差。为满足感值设计要求,该文提出一种基于结构参数分析和蒙特卡洛法的旋转式可调电感设计方法。首先,该文利用共轴圆环首次建立旋转式可调电感的解析模型,并在所提模型的基础上分析电感结构参数对可调电感感值的影响,包括导线半径、转子半径、定子半径、转子线圈匝数、定子线圈匝数。进一步,该文提出一种基于蒙特卡洛法的旋转式可调电感设计方法,并利用电感结构参数影响改进算法提高搜索精度和收敛速度。最后,仿真和实验验证该文所提方法具有设计精度高和收敛速度快的优点。该设计方法可有效减少电感迭代设计所需的时间和材料成本。The traditional design method of rotary adjustable inductance relies heavily on physical iteration.This method has poor timeliness and economy.To meet the design requirements of rotary adjustable inductance,this paper proposes a design method of rotary adjustable inductance based on structural parameter analysis and Monte Carlo method.First,the analytical model of the rotating tunable inductance is established for the first time by using the coaxial ring.Based on the proposed model,the influence of structural parameters on the inductance value is analyzed,including wire radius,rotor radius,stator radius,rotor coil turns and stator coil turns.Furthermore,this paper proposes a design method of rotary adjustable inductance based on Monte Carlo method,and optimizes the algorithm by using the influence of inductance structure parameters to improve the search accuracy and convergence speed.Finally,simulation and experiment verify that the proposed method has the advantages of high design accuracy and fast convergence speed.This design method can effectively reduce the time and material cost required for the iterative design of inductors.
