摘要:
针对应变管压力传感器的不足，该文设计了一种位移式超高压测量装置，该测量装置的弹性体是半球封头与厚壁圆管的组合结构。工作时，弹性体将压力转换成位移，使用高精度位移传感器测量出弹性体的轴向位移，建立压力与位移的关系。该测量装置的工作范围和性能主要由弹性体的结构和材料决定，因此，对弹性体的结构、线性进行了有限元仿真和分析。最后通过实验测得静态性能。结果表明：该测量装置具有良好的线性，满足静态超高压测量需求。
Abstract:
Aiming at the shortcomings of the strain tube pressure sensor, a displacement type ultra-high pressure measuring device is designed. The elastic body of the measuring device is a combined structure of a hemispherical head and a thick-walled round tube. When working, the pressure is converted into displacement through the elastic body, and the axial displacement of the elastic body is measured with a high-precision displacement sensor to establish the relationship between pressure and displacement. The working range and performance of the measuring device are mainly determined by the structure and material of the elastomer. Therefore, the finite element simulation and analysis of the structure and linearity of the elastomer are carried out. Finally, the static performance is measured through experiments. The results show that the measuring device has good linearity and meets the requirements of static ultra-high pressure measurement.
