摘要
本文利用普通声卡作为应变数据采集卡,以Borland公司的C++Builder为开发平台开发的虚拟式动态应变测试仪,具有滤波、标定、数据存储、历史波形播放以及频域分析等功能,使用者可以方便地观察和分析处理实验结果,适用于较高精度要求、中低频的动态应变测试。
The virtural dynamic measurement using the normal sound card as the dynamic data collection card at C＋＋Builder development platform in the Borland company,has many functions,such as filtering,labeling,data storing,wave displaying,frequency domain analyzing.Users can easily observe,analyse and deal with experiment results.The measurement instrument is suitable for the more precision and medium-low frequency dynamic strain measurement.
