Zusammenfassung: | The invention relates to the technical field of nuclear reactor structural mechanical simulation calculation, in particular to a C-shaped sealing ring spiral spring stiffness equivalent calculation method. The method comprises the following steps: 1, calculating a compression rebound characteristic curve of a spiral spring base body; the method comprises the steps that 1.1, plane three-dimensional finite element models of a spiral spring base body and upper and lower rigid flanges are established; step 1.2, performing grid division on the spring and the flange plane by adopting a hexahedron and a shell grid respectively, and defining material attributes; 1.3, writing a post-processing file; 2, calculating a compression rebound characteristic curve of the O-shaped ring under the initial thickness; and step 3, calculating to obtain the wall thickness of the O-shaped ring after rigidity equivalence. An inner side spiral spring base body is equivalent to an O-shaped ring with a certain thickness, so that the prob |
