摘要

A mathematical model is constructed for the vibration analysis of the reactor pressure vessel using a discrete mass model with eight degrees of freedom. The effect is analysed of changes in the flexibility coefficients on the amplitude frequency characteristics of vibrations, the influence of the number of main circulating pumps on the vibration of the reactor vessel and the effect of pressure changes and changes in coolant temperature on the frequency spectrum and amplitudes of vibrations of the core internals.
