Influence of Ultrasound on Friction Induced Vibrations during Tightening of Bolted Joints

Authors

The assembly of bolted joints is often based on the assumption that the joint has been assembled as the design guidelines prescribe. However, during the tightening process, errors can occur, some of which can be affiliated with friction-induced vibrations. In order to improve the automated tightening process and reduce the influence of friction-induced vibrations, an additional high frequency torque is applied to the bearing of the bolted joint. This leads to a significant increase in tightening efficiency, lower tightening torque, and lower pretension force increments during the tightening process.
