Research on High Frequency Sine Wave Pressure Generating Device

This paper mainly aims at the dynamic characteristic calibration system of pressure sensors used in special fields such as aviation, and designs a sine wave pressure generator that can generate high frequency and high amplitude pressure signals. The sine wave pressure generating device is the core component of the pressure sensor dynamic characteristic test system. This paper introduces the design of the calibration system and the working principle of the sine wave generating device. The core component model is established by SolidWorks three-dimensional modeling software, and the simulation is carried out by Fluent fluid simulation software. The results show that the generated waveform has obvious sine law, which verifies the feasibility of the device. In the later stage, the optimization design can be carried out on this structure, and then the ideal sine wave pressure wave is obtained, and the physical design is finally completed.
