摘　　要：磁控形状记忆合金(MSM)是一种新型具有形状记忆功能的合金材料,不仅变形率大,易于控制,动态响应速度高,而且功率密度大和机电能量转换效率高,特别适合于制造高精度的运动与位置控制执行器。该文首先介绍MSM材料在磁场作用下的变形机理与磁控特性,然后分析利用仿生学蠕动原理将MSM小步距的位移累加形成直线电机所需要的大行程的工作原理,而后论述蠕动型MSM直线电机的设计与控制方法,最后给出样机的试验结果。The magnetically controlled shape memory alloy (MSM) is a new type of shape memory alloy, which has not only large shape variation and fast dynamic response but also high power density, and high efficiency of electromechanical energy conversion. This material is particularly suitable for applications of high precision motion and position control. In this paper the shape variation mechanism and magnetically controlled characteristic of MSM material, the operation principle of inchworm type MSM linear motor as well as the design and control method of the motor are introduced. The experimental results of an inchworm MSM prototype linear motor are also presented.
