METHOD FOR GENERATING VIBRATION INDUCTION OF STEAM GENERATOR USING COMBINATION OF VIBRATION CHARACTERISTICS AND EXPERIMENTAL PARAMETERS OF HEAT TRANSFER PIPES

摘要

PURPOSE: A method for generating vibration induction of a steam generator using combination of vibration characteristics and experimental parameters of heat transfer pipes is provided to check feasibility of a floating induction vibration analysis and estimate adaptability of the secondary floating distribution analysis result for the steam generator. CONSTITUTION: After selecting the heat transfer pipe, which is an estimation object for the floating induction vibration, from the steam generator, an intrinsic vibration frequency and a vibration mode shape of the heat transfer pipe are determined through a finite element model analysis(S12). The floating induction vibration analysis is performed by using the determined intrinsic vibration frequency and vibration mode shape information(S13).
