高g值加速度传感器灵敏度标定研究

A study on Sensitivity Calibration of A High-g Acceleration Sensor

本文进行了高g值加速度传感器灵敏度的标定研究。采用轴向冲击Hopkinson杆,杆上产生的应力波作为标定加速度传感器的冲击脉冲。通过实验验证、理论分析和计算表明,这种标定方法是可行的,并给出了系统的标定误差和分析误差的方法。

A new method of Calibrating high-g acceleration is studied in this paper. A Hopkinson bar is impacted axially. The compressive strain wave travelling in the Hopkinson bar is used as pulse to calibrate acceleration. The validity of the method is verified by experimental and theoretical calculation. On the other hand, the calibration error and method of error analysis are given.
