Abstract
The increase in the extent and degree of complication of the geometry of the branched pipelines of nuclear power stations has led to the appearance of natural forms of vibrations with frequencies that cannot be determined by the traditional combined experimental-computational method. This has made it necessary to develop new approaches to the experimental determination of the dynamic characteristics and to the selection of the boundaries of the design plans. Through use of the proposed correction to the technique and algorithm used in the estimation of the seismic stability of pipelines it has been possible to increase the precision with which the lowest frequencies of the natural vibrations are determined and, in certain cases, to also reduce the volume of operations through “targeted” testing performed at sites of expected maximal amplitudes of the lowest forms of vibrations.
