| Zusammenfassung | A newly developed measuring device allows the generation and measurement of arbitrarily directed forces and moments. This device consists of a driving unit for generating the loads and a measuring unit for the accurate measurement of the acting components. Both units are realized as hexapod structures with the same geometry but mirrored arrangement. The measurement uncertainty of the multi-component calibration device depends on different influence quantities, the most important are: the hexapod geometry, the force measurement in the force transducers and the distance from the measuring hexapod to the transducer which is to be calibrated. The paper deals with the first of the three topics, namely the characterization of the hexapod. It is shown that the geometry must be measured with an uncertainty of 0,01 mm or even less. A procedure for the co-ordinate measurement of the hexapod components is proposed and will be realized. Knowing the uncertainty contributions from all of the quantities mentioned above the measurement uncertainty of the device can be calculated. |
