摘　　要：基于对冲击响应谱测量仪的校准方法研究和分析,结合现场条件使用电信号比较测量的方式,采用合成小波作为冲击响应谱时域瞬态波形的合成波形,实现冲击响应谱测量仪电信号的输入,其输出通过与标准冲击响应谱输出比较进行校准。文章最后采用校准装置模拟输出标准电压信号作为输入,比较测量仪输出值和理论值之间的误差来验证方法的可行性。This article is based on the research and analysis of the calibration method for the shock response spectrum measuring instrument,combined with on-site conditions using the method of comparing electrical signals for measurement.Synthetic wavelets are used as the synthesized waveform of the time-domain transient waveform of the shock response spectrum,realizing the input of the electrical signal of the shock response spectrum measuring instrument.Its output is calibrated by comparing it with the output of the standard shock response spectrum.At the end of the article,a calibration device is used to simulate the output standard voltage signal as input,and the error between the output value of the measuring instrument and the theoretical value is compared to verify the feasibility of the method.
