波纹管正弦压力发生技术研究

针对压力传感器在低温环境下的动态校准需求,以波纹管为核心元件,设计了一种正弦压力发生器,其在常温和低温环境下都具有良好的密封性,生成的正弦压力范围能够覆盖正压与负压。通过改变正弦压力发生器的各项结构参数并进行实验,经分析验证,最终得到了计算正弦压力幅值的经验公式,确定了波纹管作为正弦压力发生器的可行性。

Technical Research on Sinusoidal Pressure Generation of Bellows

Aiming at the requirement of dynamic calibration of pressure sensor in low temperature environment, the paper designs a sine pressure generator with bellows as the core components. The sine pressure generator has good tightness at either room temperature or low temperature and it can generates pressure ranging from positive to negative. Based on the adjustment of the structural parameters of the sine pressure generator and the further test, followed by the theoretical analysis of the experimental data, the empirical formula for calculating the amplitude of sine pressure is obtained. The feasibility of bellows as sine pressure generator is proved.
