Abstract

This paper describes the development of a torque calibration machine, based on a reference system, with a measurement range up to 400 kN·m and a target expanded relative measurement uncertainty of 0.1 %. Several factors that have to be considered as contributing to the uncertainty of measurement are discussed. The paper deals with multi-disc couplings, reference transducers and other mechanical components that are used to implement this calibration system.
