摘要： 介绍一种由两根平行的磁致伸缩棒组成的力矩激振器,并提出了它的声学和磁学方面的设计.对三种不同结构的激振器分别以并行和串行磁路结构的磁偏置进行了分析和研究,为优化力矩激振器的设计提供了依据.

关键词: 力矩激振器, 磁致伸缩棒, 弯曲波, 互功率谱方法

Abstract: A prototype moment actuator is introduced. It consists of two parallel rods of giant magnetostrictive material. Some design considerations both on acoustics and magnetics are presented. Magnetic biases for three prototypes with parallel and series magnetic paths, respectively, are examined in order to optimize the design of the moment actuator.

Key words: magnetostrictive rod, moment actuator, bend wave, cross-spectrum method
