| 摘 要： | 为实现超磁致伸缩薄膜(GMF)在微气体传感器领域的应用,需要研究其在气敏涂层条件下的磁致伸缩特性.以几何非线性弹性理论为基础,将磁致伸缩效应等效为GMF上体积力作用下的变形效应,建立了具有气敏涂层的悬臂梁式结构双层GMF低磁场下静态磁机耦合模型,解析了GMF悬臂梁末端的磁场与位移的数学关联.通过对双层薄膜TbDyFe/PI/SmFe和TbDyFe/Cu/SmFe进行试验,验证了磁场与位移数学关联的正确性.结果表明,曲线模型有较好的预测性,具有气敏涂层的GMF表现出更好的磁致伸缩效应.

| Abstract: | Study on the magnetostrictive characteristics of giant magnetostrictive thin film(GMF) with gas sensitive layer is prerequisite to implement its application to micro-gas sensor field.Based on the nonlinear elastic theory and the assumption that the magnetostrictive effect is equivalent to the effect of body force loaded on GMF,a low magnetic field static magnetomechanical coupling model of cantilever double layer GMF with gas sensitive layer is established and mathematics relationship between magnetic field... |
