摘要
ＳＭＡ（形状记忆合金）是本世纪六十年代出现的一种功能材料，具有广阔的应用前景。目前，ＳＭＡ主要用作工程材料，如管接头、工程弹簧等。本文试图利用ＳＭＡ的形状记忆特性，制作微小的功能夹持器，用于微机械零部件的装配中；并从马氏体热弹性变形出发，对这种ＳＭＡ微夹钳的设计原理、动力学特性、变位量的可控性及其与温度的关系进行了深入的研究。在文章最后，讨论了ＳＭＡ微夹钳工作过程中的能量转化关系。
Shape Memory Alloy(SMA) is a kind of functional marterial which began to appear in 1960s.It has great applications in industry field.It used to be made as pipe connecter、engineering springs etc.We try to manufacture tiny part with SMA,and use it as functional clamp in MEMs assembly.Based on the constitutents of the alloy、clamp openess temperature corresponding relation and thermal elastic transformation,the work principles、dynamic characteristics of the SMA microclamp is introduced in this article.At last we discuss the energy tansform relation during the clamp working process.
