摘要
动态应变仪的计量设备包括标准动态应变信号的产生及该信号通过动态应变仪后的参数测量两部分。测量仪器可用适当精度的通用数字电压表，而标准动态应变的产生则是尚未很好解决的问题。从动态应变仪的工作原理出发，研究了动态应变模拟信号的产生方法及其设备。
Dynamic strain amplifier metering devices include two parts which are generating standard dynamic strain signal and meauring the parameters of the singal after it through dynamic strain amplifier.Measuring apparatus can use general digital voltmeter with appropriate accuracy, but generating standard dynamic strain signal is a problem which hasn't been well solved. This paper will research the method and devices of generating dynamic strain simulative signal from the working principle of dynamic strain amplifier.
