Abstract: Precise torque measurement in nacelle test benches increases the demand for an expansion of the torque measurement range up to several MN·m and a torque transfer standard. To this end, a 5 MN·m torque transducer was acquired. However, a traceable torque calibration is only possible up to 1.1 MN·m so far. This calibration is presented and discussed in this paper. In order to fully characterise the 5 MN·m torque transfer standard, a finite element analysis of the calibration setup is performed and validated using the gathered measurement data. Moreover, the Young's Modules of the deformation body was determined using a force standard machine and a laser interferometer to acquire the longitudinal displacement of the deformation body due to compression. An estimation of the measurement signal over the entire measurement is given considering the partial range calibration results and the influences on strain gauge based measurements.
