摘　　要：基于超磁致伸缩材料的磁致伸缩效应,设计了一种以超磁致伸缩材料(Terfenol-D)作为驱动元件的旋转驱动器,并对该旋转驱动器的输出特性进行了实验研究。采用激光位移传感器、dSPACE控制器和任意波形发生器等,搭建驱动器实验测试平台,测试旋转驱动器的输出转速与锯齿波驱动信号、驱动电流和电流频率的关系。研究结果表明:在一定范围内,驱动器的转速随着驱动电流和电流频率的增加而增加,而锯齿波驱动信号的改变对转速的影响较小。在3 A、200 Hz的缓升速降锯齿波电流信号激励下,驱动器的转速最高可达13.462 r/min,为磁致伸缩旋转驱动器的设计与应用提供参考。Based on the magnetostrictive effect of giant magnetostrictive materials,a rotary actuator with giant magnetostrictive material(Terfenol-D)as the driving element is designed,and the output characteristics of the rotary actuator are experimentally studied.Using a laser displacement sensor,dSPACE controller and an arbitrary waveform generator,the drive experimental test platform is set up to test the relation between the output speed of the rotary drive and the sawtooth drive signal,drive current and current frequency.The research results show that within a certain range,the drive speed increases with the increase of drive current and current frequency,while the change of sawtooth wave drive signal has little effect on the speed.Under the excitation of a 3 A current with 200 Hz frequency and slow rising and fast falling sawtooth current signal,the drive speed can reach up to 13.462 rad/min,and it provides a basis for the design and application of magnetostrictive rotary actuators.
