| 摘 要： | 提出了预压水激波管动态校准方法。通过施加预压给水激波管产生的脉冲信号,在水激波管所产生的频率丰富的脉冲信号基础上叠加不同的静态预压,利用准δ脉冲校准原理,对高压测试系统进行动态校准。对3种高压传感器的测试数据分别建立了数学模型,进行了频谱分析,得出了3种高压传感器的频率响应特性。

| Abstract: | The pre-pressure water shock tube dynamic calibration method is put forward.The quasi-δ pulse calibration theory is used to calibrate the high pressure measurement and testing system,and the dynamic character of this system is obtained by adding several static pressures on the multiband frequency pulse signal produced by the water shock tube.It is used to do all tests,data of response of three high pressure transducers are acquired,dynamic character mathematic model is established respectively,and its spectrum is analyzed,so that the frequency response of calibrated transducer is known. |
