摘要：

If a shape-memory alloy (SMA) thin strip is applied to elements subjected to torsion, a rotary driving element with a simple mechanism can be developed. Torsion, recovery torque and torsion fatigue tests were carried out for a TiNi SMA thin strip. It was found that torque and recovery torque both increase in proportion to the angle of twist and temperature, and that the recoverable strain energy increases in proportion to temperature, while dissipated work decreases slightly with an increase in temperature. Fatigue life decreases in proportion to the angle of twist.
