对无偏置磁场时低频(0～20Hz)范围内致动器的输出位移和致动器中Terfenol-D棒的伸长量同时进行了实验测试,并分析了致动器输出位移与Terfenol-D棒伸长量之间的关系.实验主要进行了交流输入电流频率一定时改变输入电流值和交流输入电流值一定时改变输入电流频率两种情况.分析实验结果可知,致动器的输出位移比致动器中Terfenol-D棒的伸长量小,器件有机械损耗,可见器件的结构设计有很重要的意义.为发挥Terfenol-D棒的性能,提高器件效率,可以优化结构设计.该实验研究结果对致动器的设计、优化具有一定的指导作用.

This paper addressed the experimental study about the relation between the output displacement of an actuator and the elongation of Terfenol-D rod in the actuator when low frequency(0～20 Hz) without bias magnetic field.Experimental tests are done separately,1) increasing input current value when AC input current frequency is fixed,2) increasing input current frequency when AC input current value is fixed.Through analyzing experimental results,output displacement of the actuator is smaller than the elongatio...
