Abstract To improve the calibration accuracy of force sensors used in quasi-static environment, a centrifugal dynamic force calibration device based on servo drive was developed. The device had a direct drive servo motor to drive and control the mass block for centrifugal motion, and outputted controllable dynamic force through bearingless transmission mechanism. The dynamic model was established and validated by experiments, and the measurement repeatability and dynamic response performance were experimentally studied. The experimental results showed that the repeatability of the calibration device was better than 1% at medium and high rotational speeds, and the calibration device could accelerate to the rated speed 500 r/min and output 3.8 kN force in 0.242 s.
