S. Baumgarten, D. Röske, H. Kahmann, D. Mauersberger & R. Kumme
This article describes the design of a measuring facility which can be used to investigate and calibrate friction coefficient sensors. These measuring devices are used to measure the prestressing force and the tightening torque and/or the friction torques of bolted joints. The measuring facility described here enhances a 1-MN deadweight-type force standard machine (fsm). In addition to the force which this system can realize with a very small expanded relative uncertainty of 0.002 % (k...
