Design and Realization of Portable Vibration Calibrating Instrument
Portable vibration calibrating instrument is a kind of portable vibration measuring instrument, which not only can be used for calibrating many sorts of vibration sensors including acceleration, speed, displacement sensors, but also can calibrates vibration measuring instrument, vibration monitoring system and data acquisition system composed of these sensors. This system is mainly composed of signal generator, power amplifier, vibrator, standard piezoelectric acceleration sensor, charge amplifier, A/D converter module, control and display module. It has the characteristics of small volume, high accuracy, simply operation, convenient usage etc., and can be applied in the field or laboratory. Firstly this paper gives the working principle of this system. According to this, a mathematics model about it is established, from which the calculation formula of each parameter is deduced. Then the design and realization of each function module is illuminated. Finally, the system testing is carried out and the testing data is obtained too.
