Quantity traceability of falling weight deflectometer
Falling weight deflectometer (FWD) is widely used in traffic transport industry. In order to solve the traceability of FWD, the definition of deflection was studied, the use and measurement of FWD was thoroughly analysed, and the measurement parameters were determined.

| description | Falling weight deflectometer (FWD) is widely used in traffic transport industry. In order to solve the traceability of FWD, the definition of deflection was studied, the use and measurement of FWD was thoroughly analysed, and the measurement parameters were determined. Calibration device, standard foundation, and experimental environmental conditions of FWD was set up. The measurement uncertainty of the calibration equipment has been analysed. Through the test of the typical FWD, the performance of the calibration equipment is tested. Through the establishment of the traceability chain of ‘ Absolute normal low frequency vibration standard device-FWD calibration equipment-FWD’, it can meet the calibration/verification requirements of FWD. |
