摘要

磁质伸缩Terfenol-D棒是预装螺栓应力，永磁体偏置磁场，将磁质伸缩Terfenol-D棒施加在径向磁场上，当向激励线圈传递激励电流时，线圈内部就会产生随磁场变化的磁场，磁场中的电流在Terfenol-D棒可以产生运动，从而促进声板。

Finite Element Model Verification Magnetostrictive Terfenol-D Transducer

Magnetic mass scaling Terfenol-D rods are preloaded bolt stress, permanent magnet biased magnetic field, the magnetic mass scaling Terfenol-D rods on the radial magnetic field, when to excitation coil pass excitation current, inside the coil is produced along with the changing magnetic field, current in the magnetic field Terfenol-D bar can produce movement, to promote sound plate.
