Background: It is difficult to accurately simulate the non-continuous structure in reactor equipment system.Purpose: In order to investigate and simulate the non-linear characteristic of core barrel alignment plate.Methods: In this paper
a finite element model of core barrel alignment plate interface is established to investigate the non-linear analysis technology.Results: The elastoplastic deformation characters
which are obtained using finite element analysis by ANSYS software
are prepared as inputs for reactor equipment system model.Conclusions: The method used in this paper has certain referential significance for simulating the contact between non-continuous structures.
