将激振器改制为压电加速度计校准器

The Piezoelectrical Accelerometer Calibrator Remanufacturing with Type PR9270 Vibration Exciter

本文阐述了激振器的工作原理和特点 ,而且说明了如何将它改制成校准压电加速度计的小型振动台。利用这种振动台能够可靠地校准压电加速度计 ,其准确度优于 4%。

This paper describes the operation principle and character of type PR9270 vibration exciter.It explained how to remanufacture the type PR9270 vibrator exciter to Piezoelectrical accelerometer calibrator. Using the little vibration shaker, the user can reliably calibrate the piezoelectrical accelerometers. It′s accuracy can be better than 4%。
