a new fiber optic current sensor based on a fiber optic bragg grating and a magnetostrictive rod is reported.
本文提出并实验验证了一种利用新型材料制造的光纤电流传感器。
in order to obtain high displacement control accuracy, a load stiffness that is greater than that of rare earth giant magnetostrictive rod must be considered in design.
设计中应考虑一个较磁致伸缩棒刚度大得多的负载刚度,才能获得高精度的位移控制。
using the proposed model, the relation between the magnetic flux density in the air of the giant magnetostrictive force sensor and the value of force applied on the magnetostrictive rod is calculated.
