中文摘要：

针对无线电能传输系统中感应装置如何自动定位的问题，分析了感应装置之间的横向错位对耦合系数的影响，通过大型有限元软件COMSOL对整个磁芯线圈进行仿真分析，并进行实验验证。结果表明：感应装置之间的耦合系数随着感应装置横向错位的增大，呈现先减小后增大再逐渐减小的变化趋势。这一理论成果对整个系统的效率检测有一定的积极作用，有助于感应装置自动跟踪定位系统的研究。

英文摘要：

Aiming at the problem that how to locate the induction devices′position automatically in the wireless power trans-mission system, the influence of the transverse displacement of the induction devices on the coupling coefficient be-tween the induction devices is analyzed, and the whole core coil simulation analysis is been done by the large-scale finite element software COMSOL, which have also been verified through experiments. The results show that the coupling coefficient between the induction devices decreases first, then increases, finally decreases with the in-crease of induction devices′transverse displacement. The theoretical result has positive effect on the efficiency measuring of the whole system, and which is helpful to the research on the automatic location of induction devices.
