摘要

This study aims to design and implement an experimental set-up to make property assessment of NiTiNol Shape Memory Actuator Springs. Having the right material characteristics for Nickel Titanium based alloy, shortly named in industry as NiTiNol, is very important at determination of application areas and performing simulations with analytical and numerical models. An experimental set-up having load cell and sensitive displacement measurement device has been prepared to determine SMA basic characteristics. In addition to this experimental set-up, a control and power unit is used to reach at aimed control values. Measurement has been performed using a spring, which is made of NiTiNol material as shape memory alloy. SMA spring undergoes deformation with weight effect and it returns to original shape by heating with electrical current. The effect of the current data and different geometrical properties of springs used in experiment on the heating time, displacement. Properties such as wire diameter, spring diameter and number of turn of the spring have been obtained experimentally and numerically during heating and cooling processes..
