Analysis of Operational Loading Spectra and Cumulative Damage in Screw Joints

详细

The aspects of evaluating cyclical durability of screw joints are considered by the example of the main joint of the VVER-1000 nuclear reactor with a given record of operating load. Four variants of design are presented. The nonconservative essence of case three is noted. In the fourth case, the refined design requires additional in-service steps to guarantee the cyclic durability of the main joint pins.
