| Abstract: | The investigated calibration system of dynamic pressure measurement with response frequency less than 1 kHz includes two parts:a broken-film dynamic pressure signal generator and an acquisition-analysis system.Many experiment swere carried out for investigating frequency components produced by the signal generator of different lengths,which indicated that the signal generator,under first-order resonant frequency,can produce sufficient frequency components(0.5-1.5 kHz)as exciting resources.Moreover,the calibration system was used for dynamic calibration of three pressure probes of different lengths with a pressure sensor respectively.Meanwhile a particular way is adopted to obtain precise frequency response charact eristics only by measuring the pressure probe output.It is shown that the calibration system is simple,reliable,and applicable. |
