Negative Step Dynamic Torque Calibration Machine

• Abstract:

  The paper develops a negative step dynamic torque calibration machine and illustrates its working principle and critical technologies. The use of retracting actuators reduces significantly the fall time of the negative step torque, whereas air bearing yields high transfer accuracy of the dynamic torque. The experimental study is conducted and the results show that the fall time of the step torque reaches to millisecond level and the dynamic response up to 5800 Hz can be excited. Through uncertainty analysis, the expanded uncertainty of the presented calibration machine is better than 5 % (k = 2).
