摘要
首先通过对超磁致伸缩致动器系统结构以及输出滞回特性的分析,指出优化致动器机械结构和电气参数配置是减小滞回的关键.进而对致动器系统 3 个可能的滞回特性影响因素:轭铁磁导率、弹簧刚度、磁场强度变化率进行分析与实验研究,探寻使致动器滞回特性减小的有效途径.
This paper points out that optimizing the machinery and electric parameters of the actuator are pivotal to minish the hysteresis through the analysis for the system structure and outputting hysteresis of the giant magnetostrictive actuator. Then the analysis and experimental study are made about three possible factors to affect the hysteresis of the actuator sys- tem, such as the magnetoconductivity of yoke、the stiffness of spring and the change rate of magnetic density, the ways in effect which minishes the hysteresis of actuator are searched after.
