- Abstract:
- A new multi-component facility for force and torque, which can simultaneously realize precise axial force (Fz) and torsional moment (torque, Mz), is being developed in PTB. Moreover, precise two-axis measuring devices (force-torque transducers) as transfer standards must be also developed for the establishment of the measurement traceability of screw testing machines. Authors have calibrated a new-developed force-torque transducer in each direction of force and torque, separately. The crosstalk matrixes have been obtained by ordinal way, where the normal square-inverse matrix (2 by 2) was used. In this paper, authors tried to obtain the crosstalk matrix by means of another approach, pseudo-inverse matrix, where the data was used as many as possible (2 by 18 or 2 by 26), and the useful crosstalk matrix could be determined in one value.
