摘要

研究了一种压阻式三轴高

加速度计的霍普金森杆法测试实验及其数据处理方法。被测加速度计安装于标定杆的端部

从高压气舱中射出的子弹高速撞击标定杆

所产生的冲击以应力波的形式在标定杆中传播

并可以通过安装在杆中部的应变计记录。通过比较应变计的输出和加速度计输出的积分

可以计算得出被测加速度计的灵敏度。利用这种标定方法

测试了一种压阻式单片集成三轴高

g加速度计的Z轴单元和X

轴单元的灵敏度

测试结果分别为(2.18 μV/

)/5 V和(2.15 μV/

)/5 V。这一测试结果与利用自由落杆测试系统得出的测试结果基本吻合

表明本文所采用的测试系统及实验数据处理方法是可信的。

Abstract

The characterization of a triaxial piezoresistive high-

accelerometer by a Hopkinson bar and a data processing method are discussed. After fixing the accelerometer on the end of a calibration bar

the projectile launched from a barrel strikes the calibration bar at a high speed. The impact propagates in the calibration bar in the form of stress wave

which is recorded by a strain gauge fixed in the middle of the calibration bar. The sensitivity of the accelerometer can be obtained by comparing the output of the strain gauge and the integral of the accelerometer output. Using this method

the sensitivities of the

-axis element and

-axis element of a monolithic triaxial piezoresistive high-

accelerometer is characterized by (2.18 μV/

)/5 V and (2.15 μV/

)/5 V

respectively. The test results are coincident with the previous results by dropping-bar test system

which shows that the characterization system and the data processing method used in this paper are reliable.
