Application of SMA materials in aerospace

Abstract

The various characteristics of shape memory alloys, such as hyperelasticity, memory alloy effect and so on, make shape memory alloys become a new type of material with broad engineering applications. These components developed based on the characteristics of shape memory alloys are not only used in the aerospace field, but also in various fields such as bridges and railways, and can be used for various purposes such as bridge vibration control and intelligent hybrid control. This article mainly introduces several characteristics of shape memory alloys, and explains the practical application and development prospects of shape memory alloys in the aerospace field. Based on these studies, this article studies the characteristics of shape memory alloys through equation calculus and ANSYS simulation experiments modeling. It can be foreseen in the future that with the development of intelligent control technology, shape memory alloy structures will have a larger operating temperature range, more precise structural control, and will be applied in a wider variety of spacecraft structures.
