Vorstellung einer sensorintegrierten Schraube zur Bestimmung der Gesamtzusatzspannung Presentation of a sensor-integrated bolt for determining the total additional stress

A newly developed sensor-integrated bolt is presented that is capable of measuring both axial
force and bending moment in the bolt shaft. The solution presented integrates four strain
gauges into the bolt shaft without significantly altering the mechanical properties of the bolt.
The new evaluation method presented for the three non-centrically positioned strain gauges
makes it possible to determine the total additional stress in the bolt connection.
