- Abstract:
- Fatigue testing machines are widely applied in industry. For satisfying the increasing demands for dynamic force calibration of fatigue testing machines, a series of researches and experiments on dynamic force standards and methods have been carried out by NIM. A set of calibration device, which is composed of strain-gauge force transducers/ calibration bars and a data acquisition & signal conditioning device, was developed for dynamic force calibration of fatigue testing machines. The typical dynamic force standards and methods, which were used for evaluating dynamic characteristics of the calibration device, are introduced. The experiment results are analyzed and the dynamic characteristics of the calibration device are determined. It is concluded that the calibration device has good dynamic characteristics in the low and medium frequency ranges and satisfies the dynamic force calibration requirements of fatigue testing machines.
