Abstract:
Static calibration of uniaxial force transducers is performed with force standard machines which ideally generate a downward vertical force. However, these machines can be subjected to parasitic components, such as side forces and bending moments, which are transferred to the transducer under calibration. These components, mainly due to the not perfect verticality or alignment of the applied force, affect the calibration results, thus they should be estimated. In this work, parasitic side forces and bending moments are applied to six transducers by tilting and misaligning them with respect to the vertical gravitational force. Sensitivity coefficients of these parasitic components are obtained to be included in the uncertainty budget.
