    Abstract:

    In view of the status that the time of airborne vibration transducer calibration is long and the efficiency of calibration is low, the solution proposed in this article is adding a switching table on the shaking table..Through indepth research of CS18MF intermediate frequency calibration system, design and product the switching platform, and use ANSYS software to do the natural modal analysis, then get the resonance frequency. It is concluded that the natural frequency is more than 39 kHz will resonate, far higher than the required frequency of the airborne vibration sensor. Through laboratory test shows that various types of vibration sensor can installed on the switching table and multiple sensors can be installed at the same time to calibration. The switching platform used for airborne vibration calibration can greatly improve the work efficiency and the calibration accuracy can meet the requirements of less than 5%.
