压电式加速度传感器在高冲击环境下的零漂分析

Analyse Zero-drifts of the Piezoelectric Accelerometer in Rapid Impact

为了抑制侵彻加速度测试中发现的压电加速度传感器零漂现象,减小其对测试结果的不利影响,从传感器自身和传感器后续电路两大方面,我们分析了测试系统可能产生零漂的各种原因,并且针对引起零漂的原因提出相应的解决措施.试验证明,可以很好的抑制零漂现象.

To restrain zero-drifts of the piezoelectric accelerometer in high-impact testing and reduce its bad effect on the result of acceleration testing, analyses of the possible reasons of zero-drifts of testing system are presented in two aspects of sensor itself and subsequent circuits. Then, on the basis of actual testing environment, the relevant solution is showed. The results shows that it can restrain zero drift phenomena very well by means of effective design.
