| Abstract: | Calculation of tightening with angular control for bolted connections For high utilization of bolted connections, tightening beyond yield point of the screw is recommended – the keyword is tightening with angular control or „turn‐of‐the‐nut‐method”︁. Up to now calculations for technical design of bolted connections are due to assembly only with elastic stressing of the bolt. Therefore, assembly specifications of angular controlled tightening are formulated from experience or experiment. This paper proposes a handable method for calculation of snug torque and tightening angle and shows dependencies of most important parameters. Besides this a verification of the calculated results with experimental tests is done. Considered are most significant influences, which are bolt materials behaviour, geometry, length of plastification and friction. |
