摘要
为给形状记忆合金丝提供自动训练装置,并能实时测量其动作过程中应力、应变及内部电阻的变化,研制了基于LabVIEW和研华数据采集卡的步进电机驱动的形状记忆合金丝训练测试系统。该训练测试系统能够方便地实现不同型号形状记忆合金丝的自动训练过程,并能测试形状记忆合金丝在不同通电条件和外力条件下的性能。实验结果表明,采集到的形状记忆合金丝的数据准确性较高,并能实时地显示和存储,为形状记忆合金丝的进一步应用和控制提供了实验数据基础。
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.
