Factors Influencing Design of SMA Actuators

Abstract: Given the complex nonlinear nature of SMA responses, understanding their coupled thermomechanical responses of different components has been of significant interest for both researchers and application developers [1]. SMA component responses in different applications can be significantly affected by several factors like material compositions, component geometries, operating temperature, loading conditions, loading rates, thermomechanical history, processing conditions etc. and mostly combination of several of … Show more

“…The best combination of geometrical parameters achieved was as follows: spring with an effective diameter of 10 mm built with a 1.5 mm diameter wire and assembled with three active coils. The springs are previously manufactured by shape setting (Lecce and Concilio, 2015; Rao et al, 2015). It is important to keep disk position and equivalent stiffness in order to ensure no changes in shaft height.…”

“…For thermal treatment ( 450 ° C for 25 min) (Figure 7(b)), the springs are covered with a thin sheet metal to prevent unwinding. After thermal treatment, helical springs as shown in Figure 7(c) are obtained (Rao et al, 2015).…”
