Abstract:In view of the current situation that the range of the existing sinusoidal force calibration device can not fully meet the requirements of dynamic force calibration, a (2.5 ~ 250) kN sinusoidal force calibration device has been developed in order to expand the calibration range and reduce the measurement uncertainty of the sinusoidal force. After the development of this new device, the dynamic force traceability system in China will be more perfect and a series of high-precision sinusoidal force standards will be established based on this device.
