| Abstract: | Aiming at the demerits of time-consuming and low efficiency during the process of ultralow frequency vibration calibration,an automatic ultralow frequency vibration calibration system based on personal computer and virtual instrument was presented.The system was consisted of ultralow frequency standard vibrator,power amplifier,laser vibrometer,displacement transducer,signal generator,universal counter,data acquisition card,computer,control software,etc..The strategy which via combining the method of linear approximation and step-by-step frequency shift could make the vibrator reach the pre-set vibration level quickly and precisely.The experiment results show that the system is suitable for the calibrating ultralow frequency vibration transducers very well and improves the automation of ultralow frequency calibrating vibration. |
