虚拟仪器在测试技术实验中的应用

Application of Virtual Instruments into Experiments of Measurement Technology

随着虚拟仪器技术的发展,虚拟仪器在实验中的应用日益广泛。以悬臂梁固有频率的测量为例,将虚拟仪器技术应用于测试技术实验,设计了基于虚拟仪器的实验仪器系统,详细介绍了系统硬件、软件的构成,开发了基于LabVIEW的测量程序,增强了实验的实用性与趣味性,提高了实验的准确性,取得了较好的效果。

With the development of virtual instrument technology, there has been an ever-increasingly wide application of virtual instruments into experiments. The measuring experiment of cantilever beam natural frequency is taken as an example in this paper to illustrate the application of such a technology into experiment teaching of measurement technology. The experimenting instrument system based on virtual instruments is designed with detailed introduction made on its hardware and software. Besides, the LabVIEW-based measuring program is developed. Such a program can help to raise the accuracy of experiment and improve the interest and practicality of experiment teaching with satisfactory teaching effect achieved.
