摘　　要：为了探索引压管腔在动态压力校准中各校准方法的一致性与数据准确性,确立了以简单直管形式引压管腔开展动态特性校准的研究。采用理论和仿真的手段分析并建立了引压管腔模型,理论模型和仿真结果一致性极高。利用3种正弦压力校准装置对同一引压管腔进行了动态校准组合试验,结果表明:3种校准方法所得的动态特性与理论分析趋势一致,对于引压管腔基频的校准各试验之间偏差小于0.55%,但与基频理论值最大偏差为-3.17%。该研究将会为未来引压管腔结构设计和动态特性的补偿修正提供了一定参考依据。In order to explore the consistency and data accuracy of each calibration method in the dynamic pressure calibration of the pressure tube cavity,a simple straight-tube type of pressure tube cavity was established to carry out the dynamic characteristic calibration research.The theoretical and simulation methods were used to analyze and establish the model of the pressure tube cavity.The consistency between the theoretical model and the simulation results was very high.Three kinds of sinusoidal pressure calibration devices were used to carry out dynamic calibration for the same pressure tube cavity.Results showed that the dynamic characteristics obtained by the three calibration methods were consistent with the trend of theoretical analysis.For the calibration of the fundamental frequency of the pressure tube cavity,the deviation between the tests was less than 0.55%.However,the maximum deviation from the theoretical value of the fundamental frequency was-3.17%,and there was a large deviation from the other resonance frequencies・This study provides a reference for structural design of pressure tube cavity and compensation correction of dynamic characteristics in the future.
