基于虚拟仪器的Hopkinson压杆试验装置研制

Development of Hopkinson Pressure Bar Equipment Based on Virtual Instrument

采用虚拟仪器技术改造了高应变率试验装置Hopkinson压杆,替代传统的用于显示信号原始物理波形的数字示波器,在必要的数据采集硬件和专业化软件的支持下,实现了传统示波器的功能,体现了用软件代替硬件的思想。

It reconstructs Hopkinson pressure bar equipment based on virtual instrument for high strain rate experience, which substitutes traditional digital oscillograph used for displaying original wave, all functions of digital oscillograph are realized, and the idea of replacing hardware by software is achieved by the hands of data gather card and specialization software.
