Design and Analysis of Damping in Piezoresistive Micro Shock Accelerometer

摘要：

As in shock acceleration, there are plenty of frequency components, when one of them possesses the frequency which is equal or very close to the natural frequency of the accelerometer system, resonance will occur in the system, therefore, the moving amplitude of the beam-mass structure will be increased infinitely, as a result, the structure will be damaged. To solve such a problem, and to improve the anti-overload capability of shock accelerometers, their damping parameters should be designed properly. Taking the tri-axial piezoresistive micro shock accelerometer as a research object, this paper designs a reasonable damping ratio for the sensor, and the damping ratio controlling method is also presented. Moreover, the output response characteristics of the sensor with the designed damping parameters are presented in this paper.
