Analysis of the measurement uncertainty of a new measurement flexure calibration set-up

Abstract

A measurement flexure calibration set-up is presented in this paper. The measurement flexures under test are part of a new 5 MN · m standard torque machine measurement system at the PTB. The calibration set-up can create transversal forces up to 200 N and bending moments up to 100 N · m and respectively up to 150 N · m torque moments simultaneously. The measurement uncertainty budget of the set-up is investigated in a theoretical analysis.
