| 在动态压力测量领域中，带引压管腔的压力测量系统常被用于空间狭小、工况恶劣等情况下的压力测量，压力信号经过引压管腔传递往往发生畸变，引压管腔是降低压力测量系统频响的首要因素。本文首先介绍了带引压管腔的压力测量系统物理结构模型，阐述管腔动态特性影响动态测量机理。其次，介绍了现有引压管腔主要校准方法和装置，开展新型校准装置和方法研究，研制了一种静态压力及温度可调的校准装置。最后，利用该校准装置对带引压管腔的压力测量系统进行实验，对带引压管腔的压力测量系统的动态计量与补偿技术发展具有借鉴作用。 |

| In the field of dynamic pressure measurement, the pressure measurement system with transmission pipe is often used for the pressure measurement in narrow space and bad working conditions. The pressure signal through transmission pipe was often distorted, which becomes an important factor to decrease the frequency response of pressure measurement system. In this paper, the physical structure model of pressure measurement system with transmission pipe is introduced, and the dynamic measurement mechanism affected by the dynamic characteristics of transmission pipe is explained at first. Secondly, the calibration devices of transmission pipe and methods are introduced, a new calibration device and method is studied, and a static pressure and temperature adjustable calibration device is developed. Finally, the calibration device is used to test the pressure measurement system with transmission pipe, which can be used as a reference to the development of dynamic measurement and compensation technology of pressure measurement system with transmission pipe. |
