Outline
According to the characteristics of electronic piezo gauge, a novel strain type high chamber pressure test system is developed, which takes the end cover of the electronic piezo gauge as an elastic sensitive component. The mechanical characteristics of electronic piezo gauge shell are analyzed using the deformation theory of thick plates. The stress/strain distribution and model of the elastic sensitive components are simulated by ANSYS software, and the 50-550 MPa static and dynamic calibration experiments are also conducted for comparison. The experimental results show that the linear error, basic error, sensitivity, and measurement range of the system are 0.62%, 4.6%, 2.231 3×10-12 Pa-1, and 0-600 MPa, respectively. Therefore, the strain type high chamber pressure test system is feasible and accurate.
