| 摘 要： | 基于非铁磁性金属管的电磁耦合系统中,由于电磁场趋附效应等原因阻碍磁场穿透金属管而无法实现能量和信息的有效传输,为解决该问题,建立了系统电磁耦合数学模型,推导出管内磁场分布及次级线圈感应电压表达式,利用ANSYS软件对影响初次级耦合的敏感因素,如激励频率、金属管材料,进行了仿真分析,结果表明高电阻率的金属材料及低的激励频率,可增大系统耦合效率,且初级线圈在5 kHz至10 kHz激励频率附近工作时,次级可获得最佳感应电压.实验证明,基于上述结论设计的无线传输系统可满足负载电路对感应电压幅值及信息同步传输的要求.

| Abstract: | In the electromagnetic coupling system based on non-ferromagnetic metal tube,effective power and information transmission is difficult because electromagnetic field skin effect and other factors prevent magnetic field from penetrating the metal tube.In order to solve this problem,an electromagnetic coupling mathematic model of the system was established,and the formulas of the magnetic field distribution inside the tube and the inducted voltage of secondary coil were deduced.Multiphysics simulation software... |
