Abstract

The calibration of a multicomponent force transducers (MFTs)represents a challenge in the meganewtonrange. In fact,the generation of transversal forces and moments iscomplex since a force standard machine (FSM) is only able to apply an uniaxial force. Furthermore since MFTs are composed of multi-transducers, each one dedicated to a particular component, correlations between force and moment componentsare possible. Therefore, acalibration systemthat could simultaneously generate all force/moment components and could be suitableinevery FSMis needed. For this purpose, a coupleof tilted plates was designed. Calibration measurements were performed on a 2 MN MFT at INRiM, LNE and PTB. Exploitation matrixes and performance indicators showed good results, unless small but not negligible correlations between MFT outputs. In particularsome spurious valuesdue to the uncertainty inthe vertical force application pointinfluencedthe moment components.
