Study on a Novel Piezoelectric Accelerometer with Switch Characteristic

Abstract:

A novel piezoelectric accelerometer with switch characteristic was introduced. The accelerometer is composed of top head, cross elastic beam, base core, insulation cylinder, mass block, piezoelectric elements, and the base etc. The accelerometers structure and operating principle were presented and its mathematic model was established. Test results show that the accelerometer can filter out high frequency vibration signal, which the out signal is smooth compared with the conventional piezoelectric accelerometer, furthermore with good linearity. It can be used in the smart fuze to take the place of conventional piezoelectric accelerometer in order to recognize the target accurately.
