Abstract
The purpose of this study is to investigate fatigue characteristics of Cu-Al-Mn superelastic alloy for lumbago prevent apron and assistance tools for grape faming. The specimen was made from five Cu-Al-Mn superelastic wires of 1.7mm in diameter and 400mm in length. Specimens were made by Furukawa Techno Material Co., Ltd. The apparatus generated the power to use superelastic component. The transformation temperatures were measured by differential scanning calorimetry (DSC). The bending fatigue characteristics of superelastic components were investigated by fatigue tester. The maximum strain ration of bending fatigue test was about 3.4%. Fatigue lives of the superelastic components were about 1,300 times.
