To provide an automatic training equipment and measure the stress, strain and electric resistance in the action process for shape memory alloy wires, a stepping motor driven SMA wires system based on labVIEW and an Advantech data acquisition card was developed. SMA wires with different diameters can be trained conveniently by the present system. The performance of SMA wires in different electric currents and external forces can also be measured. The experimental results show that the acquired data of SMA wires is highly exact and can be displayed and saved in real time. These data provides an experimental basis for the SMA wires’ further application and control.
