摘　　要：通过三维有限元电磁仿真软件设计了电能无线传输实验的仿真模型,研究了电能无线传输实验的谐振特性以及传输特性.通过合理设置参量,模拟电能无线传输实验的电磁能量传输过程.通过控制变量法,研究电能无线传输过程中,实验参数对其传输性能的影响,主要包括谐振线圈的匝数、线圈的间距、谐振状态等因素对传输距离和谐振频率的影响.The resonant characteristics and transmission characteristics of wireless power transfer experiment by the three-dimensional finite element electromagnetic simulation software were researched.The electromagnetic energy transmission process of wireless power transfer experiment was simulated by reasonably setting parameters.Through the control variable method,the influence of the experimental parameters on the transfer performance of wireless power transfer experiment was studied,such as the turns of the resonant coil,the distance between the resonance coils,space between turns and so on,which affect the transfer distance and the resonance frequency.
