Abstract
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 = 2) (in the measuring range from 20 kN to 1 MN), it is the aim to generate an extremely precise torque (better than 0.005 % at k = 2) in the range from 20 N·m to 2 kN·m.
