摘要：
A finite-element method is proposed for determining numerically the characteristic frequencies and forms of the oscillations of a shell structure in a liquid. An experimental method for determining the charcteristic frequencies and forms of the oscillations of the structural elements by holographic interferometry is examined The results obtained for the characteristic frequencies and forms of the oscillations of a model of a VVER-1000 reactor pit by the finite-element and holographic interferometry methods are presented The calculations agree well with the experimental data. This shows that the computational model adopted for the oscillations of bodies in liquids is adequate and that the algorithms developed for simulating the vibrations can be verified by holographic interferometry.
