在windowsnt系统环境和labview虚拟仪器技术开发平台下，首次利用labview中的直线拟合模块、指数拟合模块以及多项式拟合模块，设计了一种对实验所得数据进行曲线拟合的方法，对三种拟合方法进行了比较，曲线拟合结果表明，多项式拟合方法相对于其它两种拟合方法效果更好；根据曲线拟合的结果可从带激励线圈的磁致伸缩换能器的输入阻抗中分离出磁致伸缩换能器铁芯在无激励电流时机械振动形成的等效输入阻抗，并由此输入阻抗确定了磁致伸缩换能器的谐振频率及其电气模拟网络参数；最后通过labview提供的网络功能，实现了基于web服务器的磁致伸缩换能器电气模拟虚拟仪器测试系统，并探讨了通过datasocket技术实现该系统网络化的方案。
