Abstract:
A hinge measurement flexure calibration set-up for stiffness measurements has been built at the Physikalisch-Technische Bundesanstalt (PTB) to estimate parasitic loads on PTB’s 5 MN·m torque standard machine (TSM). This paper describes the improvements made to a measurement flexure calibration set-up made since its first presentation. The list of measurement uncertainty influences is refined. Initial results of a combined transversal force and bending and torque moment stiffness measurement are presented and compared to a previous finite element analysis.
