In order to explore the effect of different factors on the dynamic characteristics of the pressure transmission pipe in the dynamic calibration and operation

the pressure transmission model and the relationship between vibration frequency were deduced. The parameters affecting the dynamic characteristics of the transmission pipe

including static pressure

temperature

gas medium

were established. The experimental verification of different environmental factors was carried out by using special experimental device of the transmission pipe. Results showed that the static pressure only affected the output of the transmission pipe at the resonant frequency

but increased nonlinearly with the increase of the static pressure

and had no significant effect on the dynamic characteristics; with the increase of temperature

the resonant frequency increased but the output amplitude decreased; different gas media would change the dynamic characteristics of the transmission pipe mainly depending on the sound velocity of the medium. This study provides a reference for the data evaluation and correction of the transmission pipe in the use environment.
