Design and Analysis of Release Mechanism using Shape Memory Alloy for Spacecraft

Abstract

Abstract Shape memory alloy (SMA) is used as a smart material. It is also called as Nitinol and intelligent material because it regains their original shape after deformation. It works on the principle of shape memory effect which regain their original shape after passing through different temperature phases. SMA get some more attention in incoming years due to their superior and unique properties. This paper presents design and maximum stress analysis of release mechanism using SMA. It also covers the capability and efficiency of notch bolt of Frangibolt mechanism. Its design, calculation and analysis has done in CAD software and simulation software.
