allbolzenbruch1engl.svgClamping bolt, due to dynamic fatigueClamping bolt asse-mbly in a turbine diskScrew joint acts as a clamping deviceFracture planeMajor bending of the flexure line, especially at the mounting height,during high-frequency vibrationsindicates high bending stress Minor bending of the flexure lineduring low-frequency vibrationsindicates low bending stressIf there is a clearance gap,the bolt is not damped and vibrations can occurFlexure lines during various bolt vibrationsMeasures taken to prevent rubbing can alsocause damage.
