Abstract:
The finite element software ANSYS11.0,a finite element methods codes,is used to simulate the mechanical characteristics of the Reactor Pressure Vessel(RPV) support rings under serious conditions.According to RCC-M code,the stress intensity is evaluated for the each part of the RPV support rings.The result shows that the RPV support rings satisfy the correlative criterion.This model is a more realistic simulation of the actual structure,the boundary conditions and applied loadings,effectively reducing the errors caused by model simplification.
