| 摘 要： | 研究了光纤磁致伸缩传感器的灵敏度与其磁致伸缩套层厚度的关系.从磁致伸缩应变的一般公式出发,应用力学平衡条件,可求出光纤与磁致伸缩套层粘合后的共同应变,根据光弹理论的公式,即可给出灵敏度与套层厚度关系的明确表达式.

| Abstract: | The relation between the sensitivity of anoptical fibre magnetostrictive sensor and its magnetostrictive jacket thickness is studied at length. With the general formula for the magnetostrictive strain,the common strain of the fibre glued with a magnetostrictive jacket and the condition for mechanical equilibrium can be found. An explicit expression for the relation between sensitivity and jacket thickness is then given according to the photoelastic theory. |
