摘要
设计的应力脉冲测试系统 ,用于分离式Hopkinson压杆 (SHPB)应力脉冲的测试 ,系统能实现模—数转换和数字信号的直接存储与处理 ,无需专门的数字存储示波器。该系统结构简单 ,减少了数据采集与处理的中间环节 ,结果更准确、可靠。
A new stress wave measurement system is designed, which is used in Split Hopkinson Pressure Bar (SHPB) set-up. This system can do A/D transformation. The digital signal can be saved and processed directly in Micro-Computer based on instrument. The digital memory oscilloscope does not need. The structure of this system is concision, which will reduce mesne parts of data acquisition and processing. The expermental results will be more accurate and credibility.
