Abstract

Abstract: The pressure simulation test simulates the airflow condition of the specimen in the practical working processes by precisely controlling the surrounding pressure, for the purpose of testing the ventilation efficiency and structural reliability of the specimen. In this study, to meet the demand that the pressure at a specific position can be measured during the test, a calibration method of pressure measurement via the pressure pipeline is proposed. In the calibration test, the primary pressure value that using the pressure pipeline is measured by the measuring gauge and the standard pressure value could be measured by the standard gauge. The proper fitting function could be chosen in MATLAB and a set of correction formula could be fitted by the pressure value. The as-measured value could be corrected by the formula to obtain an accurate pressure value in the subsequent test. It is verified by experiments that the calibration method can effectively eliminate the influence of the pressure piping on the pressure measurement and ensure the implementation of the pressure simulation test.

Key words: pressure simulation test, pressure pipeline, calibration test, correction formula
