摘要
利用自行设计的实验装置研究了NiMnGa合金样品静态时磁场与形变之间的关系,并且实测了交流磁场下温度、压力、磁场与样品形变的动态特性曲线,研究了NiMnGa合金样品的外特性。在此基础上,利用NiMnGa合金响应频率快、输出应变应力大等特点,设计了一种可以减少励磁功率、消除温度影响和提高控制精度的新型差动式NiMnGa合金执行器,阐述了其工作原理,制造了样机并给出了实验结果,验证了该设计方案和控制系统的可行性。
With self-designed equipment, the static relationship between the deformation of a NiMnGa alloy sample and the magnetic field is studied. The dynamic characteristics of this alloy sample under temperature, stress, magnetic field and strain are measured. As a result, a novel differential NiMnGa alloy actuator is proposed, which has fast response frequency and great output strain. The working principle of the designed actuator is explained. Experimental result shows the proposed system is feasible.
