FIELD: testing.
SUBSTANCE: group of inventions relates to devices and methods of vibration testing of on-board radio electronic equipment (REE), which is part of a cylindrical compartment, which can be used in independent tests of REE at the stages of its development and manufacturing. Fastening device is made in the form of a hollow cylinder having a base and stiffening ribs, which is part of the set, and is designed so that the length of the cantilever part of the cylindrical compartment does not exceed the value of the diameter of the compartment. Plug included in the set of accessories is made in the form of a flat thin spherical shell with the lower frequency of natural oscillations located above the upper limit of the vibration test frequency range. Said set of accessories is used during vibration tests.
EFFECT: increasing the accuracy of vibration testing by eliminating the influence of bending vibrations of the cylindrical compartment and radial vibrations of its open end on the transmission of specified parameters.
