Abstract
The disclosure discloses a measuring device for dynamic characteristics of pressure sensitive paint, including a PSP sample wafer, a dynamic pressure sensor, an oscilloscope, a light source, a photomultiplier tube, a bandpass filter, a loudspeaker, a power amplifier, and a signal generator. The disclosure further discloses a measuring method for dynamic characteristics of pressure sensitive paint. The disclosure has the following beneficial effects: by using the measuring device disclosed by the present disclosure, the continuous sinusoidal pressure wave with any frequency can be generated, and has the frequency precision that does not exceed 0.01 Hz, an optical path is not shielded, high stability is achieved, and the amplitude and phase characteristics of the pressure frequency of the PSP can be precisely captured.
