Background: For the nuclear power plant main component under design phase
the anti-seismic capability analysis should be evaluation used response spectrum analysis or time history analysis usually.Purpose: This paper attempts to get the non-linear influence because of gaps.Methods: Based on ANSYS FEM software
get the CRDM seismic result used improve spectrum analysis
which compare with the time history analysis.Results: the bending moments and shear force on each sections of CRDM housing was showed in this paper.Conclusions: The result shows that the improve spectrum analysis can get the structure dynamic characteristics
the calculation results between the improve spectrum analysis and the time history analysis are consistent
it can provide guidance on the subsequent equipment design.
