The Realization of Micro-Torque Calibration and Measurement Device

• Abstract:

  The calibration and measurement of micro-torque have long been the research focus of inertial navigation system. In this paper, the micro-torque calibration and measurement device based on knife-edge support are proposed, which combine the electromagnetic force balance and indifferent equilibrium technology to realize selfish calibration and automatic measurement. This device can be used to measure 10^-5 N·m torque of components of inertial navigation system. This paper aims to describe the basic theory and critical techniques. Uncertainty is evaluated and experiments were done to evaluate the repeatability of the device. The work is standing out in the field of international torque calibration.
