Abstract: The main working stress of the hightemperature turbine bolts and its calculation method were introduced. For a typical bolt, using the software SolidWorks, a tridimensional finite element model was established; the ANSYS Workbanch was imported to carry out the finite element stress analysis; the whole and local VonMises equivalent stress distribution of the bolt was obtained. Some reasons leading to the failure of the bolt were analyzed preliminarily from the view point of stress. The life loss of the bolt caused by the bending stress and the fastening technology was analyzed. The results of this paper are of important significance for bolt metal supervision.
