Abstract

The reliability of the dynamic qualification of structural components of a nuclear power reactor totally depends on the dynamic characterization, i.e. identification of natural frequencies, mode shapes and damping of the components. Often, the correct identification of these parameters by the experiment or analysis alone may be difficult for many cases. In this paper, the strength of the analytical modelling in understanding the experimental results and interpreting them are presented through a case study. © 2002 Elsevier Science B.V.
