摘要:
基于换能器的不同应用背景,设计了2台换能器样机,分别为应用于高频的双棒结构换能器样机和 应用于微米级抛光的四棒结构换能器样机。基于Maxwell方程组,应用有限元方法对两台多棒结构换能器 样机进行了磁场分析,确定了最佳磁路结构。研究发现,在6000Hz频率和2A励磁电流下,驱动线圈串 联的双棒结构换能器的平均磁通密度为0.879T。与其他磁路结构相比,它的磁通密度更高且更均匀,适 用于高频换能器。对四棒结构换能器进行不同激励条件下的磁场分析,结果可知A棒和C棒的磁通密度相 位相差180°,B棒和D棒的磁通密度相位也相差180°,磁通密度峰值均为0.45T。4个磁致伸缩材料棒之 间形成闭合回路,漏磁较小,具有三维位移输出,此磁路结构适用于微米级抛光的换能器。
