THE NEW 5 MN HEXAPOD-SHAPED MULTICOMPONENT BUILD-UP SYSTEM FOR FORCE MEASUREMENTS

In the framework of the EMRP Joint Research Project SIB63 “Force” with the title “Force traceability within the meganewton range”, WP2, aiming to extend the traceability of the force measurements to the higher part of the scale, a new and innovative type of Build-Up System (BUS) force transducer, with a capacity of 5MN, has been designed and realized by INRIM. It is composed by six Uniaxial Force Transducers (UFTs) and it has a hexapod-shape. It can be used to extend the scale from 1 MN to 5 MN with internal traceability for the vertical (axial) force and, thanks to his scheme, additionally provides measurements of transversal forces, bending and torsion moments. In the paper, the description of the design, of the calibration procedure and of the data analysis is provided.
