Application and Investigation of Piezoelectric Accelerometer on Vibration Measurement System

Introduced the characteristics of the piezoelectric accelerometer such as small volume,low-weight,wide measure range.Stated the technique used in vibration measurement system;analyzed the operating principle of piezoelectric accelerometer from vibration acceleration to charge;and also discussed the overall project based on piezoelectric accelerometer.The vibration measurement system consists of piezoelectric accelerometer,charge amplifier,dynamic data acquisition analysis system and so on.Acquired vibration signal can be displayed,stored,analyzed and processed in real time.Finally,the system was validated in actual measurement of road roller.
