FIELD: physics.
SUBSTANCE: in determination of bellows and tank shell natural vibrations, swinging frequency test is performed in several steps with reduction in scanning speed from that recommended by specifications to minimum magnitudes allowed by test equipment. Then, maximum scanning speed is determined by swinging frequency method whereat bellows minimum natural frequencies are defined. Now, conditions of testing tank with bellows are formed to set ranges of harmonic and random vibration tests and tanks are tested.
EFFECT: higher validity.
