差动式逆磁致伸缩应力传感器的设计

Design of differential stress sensor based on counter magnetostriction effect

基于铁磁材料的逆磁致伸缩效应,设计了一种五磁极差动式应力传感器。通过初步实验,验证了其基本磁测性能,并认为该传感器具有灵敏度较高、可用于扭矩及其它形式应力检测等特点。

*'The design of differential stress sensor with five magnetic pole based on counter magnetostriction effect of ferromagnetic materials is given.By principium experimentation basic measure performance of the sensor is validated and it can be consider that the sensor have higher sensitivity to measure and can be used to survey torque and other many kinds of stress load.
