摘要

线性能量采集器和执行器利用电磁感应原理产生电能或运动。这种执行器最常见的配置是圆柱形环形磁铁，内部有线圈或圆柱形磁铁，磁铁周围有线圈。通过一系列的数值有限元分析来设计和模拟不同的磁芯-环磁体结构，以确定最大能量转导的最佳组合。结果表明，锥形环形磁体-锥形磁芯结构具有最大的磁空间变异性，适合于最大的能量转导。该研究可应用于线性执行器、线性电磁能量采集器的设计，并可从微观尺度应用到宏观尺度。

Design and simulation of core-ring magnet configurations for maximising energy transduction in linear actuators and micro-energy generators

The Linear energy harvesters and actuators employ electromagnetic induction principles to generate electrical energy or motion. The most common configurations for such actuators are cylindrical ring magnets with coils inside or cylindrical magnets with coils surrounding the magnets. A series of numerical FEA analyses were performed to design and simulate different core-ring magnet configurations to identify the best possible combination for maximum energy transduction. It was observed that the tapered ring magnet - tapered core configuration had the highest magnetic spatial variation and thus suitable for maximum energy transduction. This study can be applied to design linear actuators, linear electromagnetic energy harvesters and from microscale to macroscale applications.
