Calculation model for pre-stressed bolted joints of slewing bearings

The presented paper describes a calculation model for pre-stressed bolted joints used to connect slewing bearings to the adjacent structures. A classical pre-stressed bolted joint calculation model is described and its insufficiencies for direct application on slewing bearings are pointed out. Finally, the suggested stress analysis is done by modelling the most loaded single bolt segment of the slewing bearing assembly, applying the preload and the working load on it. The stress determination in the bolt is done by finite element analysis.
