| Abstract: | Misalignment of torque calibration machines can cause parasitic bending loads inside the torque transducers in use. These parasitic loads may affect the machine uncertainty, specially for secondary torque calibration machines. Therefore, this study discusses the contribution of misalignment to the measurement uncertainty for a newly designed 3 kNm secondary vertical torque calibration machine. Radial axes shift up to 4 mm was applied which introduce small increased uncertainty. |
