摘要
基于电磁耦合谐振式无线电能传输技术,为电能-机械能的无线传输、转换和控制提供途径,从而为不易拖带电线的微型机器人等用电机构的供能提供便利。建立漏感等效电路并分析了系统整体性能,然后针对超磁致伸缩材料特性建立了电、磁、机械(力)场路耦合模型,并得出系统整体传递函数。实验制作了电磁-机械同步共振系统样机,其测量结果表明由示波器监测的励磁电压频率与通过上位机采集的磁致伸缩棒振动频率一致,同时实现了在间距为30 cm频率为10.07 kHz时电能-机械能的同步转换。
The method of electromagnetic（ EM） energy transmission and conversion was discussed based on resonantly coupled power transfer technology to find a solution for wireless power transmission,switching and controlling between it and mechanical energy. It brings convenience to electricity consumption of micro-robots which are difficult for towing cables. The coupled model of electric,magnetic and mechanical（ force） was established and the overall system transfer function was derived according to the properties magnetostrictive materials. The prototype of the system was produced and experimental results show that the frequency of excitation voltage from oscilloscope accords with that of rod＇s vibration from upper computer when working at 10. 07 kHz 30 cm spaced.
