Abstract: According to the method of comparison to a reference transducer, the approach for the calibration of impact acceleration is studied. Based on technology of impact excitation by pneumatic piston and technology of data acquisition by PXI bus, impact acceleration calibration device is established. The calibration software is programmed on LabVIEW, and the measurement uncertainty of device is evaluated. The calibration device can be used for national defense products shock test traceability of impact acceleration.
