摘要/Abstract

摘要： 形状记忆合金(Shape Memory Alloy,简称SMA)拥有其他金属或合金所不具备的形状记忆效应及超弹性。对形状记忆合金材料进行一定的预变形,在其形状回复过程中会产生较大的回复力。将预变形的SMA埋入结构中或连接于结构表面,当其受热回复时即可使结构形状改变。基于此原理,国内外已对智能梁结构、机翼、旋翼叶片、智能进气道、发动机舱后缘结构、可变发动机喷嘴等的形状控制进行了研究。本文在综述基于SMA结构形状控制研究的基础上,提出了若干需要进一步研究的问题。

Abstract: Shape memory alloy (SMA) has some special properties different from common metal. It can produce big recovery force during the recovery process once it was prestrained. We may embed SMA into structures and utilize the shape recovery force to change the shape. Thus, the structures can meet different requirements in different service conditions. Many scholars have carried out researches on smart beam structures, smart wings and blades, smart inlet, variable chevron, and variable nozzle. This paper reviews the progress of SMA in shape control, and puts forward some critical issues needing to be solved in engineering applications in future.

Key words: shape memory alloy, smart structures, shape control
