- Effects of Heat-Treatment Condition on Generating Force and Functional Degradation Characteristics of Single Coiled Torsion Springs Made of Shape Memory Alloy Wire
抄録
<p>The single coiled torsion spring made of Ti-Ni shape memory alloy (SMA) is expected to be used as a torsion spring that is smaller in size and has a larger displacement than torsion springs made of conventional spring materials. However, heat-treatment is necessary for Ti-Ni SMA to memorize the spring shape. Furthermore, it is well known that the shape memory and mechanical properties of Ti-Ni SMA are varied with the variation of heat-treatment condition. Therefore, spring characteristics of Ti-Ni SMA torsion spring is expected to be affected by heat-treatment condition. In this study, effects of heat-treatment condition on generating force and functional degradation characteristics of single coiled torsion springs made of Ti-Ni SMA wire are investigated. In result, the output power and functional degradation characteristics of Ti-Ni SMA torsion springs tend to decrease with the increment of heat-treatment temperature and heat-treatment time. This tendency is thought to be caused by the decrease of internal stress due to the decrease of deformation texture or precipitates with the increment of heat-treatment temperature or time. Meanwhile, fatigue life tends to decrease with increment of generating force. This tendency is thought to be caused by the increase of deformation stress due to the increase of generating force.</p>
