Construction and experimental identification of an uncertain model in computational dynamics using a generalized probabilistic approach of uncertainties

Abstract : We are interested in constructing an uncertain model of a nominal motor CSS of pressurized water reactor using a generalized probabilistic approach of uncertainties and in identifying this model using experimental measurements of the first eigenfrequencies. This generalized probabilistic approach of uncertainties allows both model-parameter uncertainties and model uncertainties to be taken into account and identified separately in the context of the experimental modal anaysis. Finally, the identified uncertain model allows statistics on quantities of interest to be estimated.
