Abstract

Abstract

To meet the test requirements in special situation,a high-g accelerometer structure with four-terminal fixed beam-island was designed. The dynamic characteristics of the accelerometer were test by using the Hopkinson bar impact calibration device. The test results show that the sensitivity of the sensor is 1.2 V/g and the linearity is 5%. The output signal is proper when impact by 2105 g. So the designed accelerometer can effectively meet the special test requirements such as high impact and strong vibration,and it can be applied to the penetration system.
