峰流速仪标定系统数学模型的研究

Study on the mathematical model of the calibration system of the peak flow meter

对峰流速仪标定系统中的空气运动进行分析,引进特征线方法,建立了峰流速仪标定系统的数学模型,编制了计算机仿真程序,仿真结果与实验结果基本吻合,证明该模型的正确性。利用该模型对待标定的峰流速仪进行了标定。

This paper analyzed the movement of the gas in the calibration system of the peak flow meter, and introduced into the characteristics method, then developed a mathematical model of the calibration system of the peak flow meter. The model’s simulating program was designed, the simulating result is verified by the experiment result, which proves that the model is correct. The model was applied to calibrate the peak flow meter.
