Реферат: eng: For launching devices and equipment (payload) into orbit they are usually placed in a foam package made of various polymeric materials. One of the functions of the foam package is to prevent low-frequency vibrations of the payload. In this connection, the problem of determining the natural frequencies of vibrations of the 'payload - foam package' system is relevant. These frequencies depend on the physical-mechanical properties and the size of the foam package, the mass and size of the payload. The paper presents the results of an experimental determination of the stiffness characteristics of the foam package materials and a computational analysis of the natural frequencies of the 'payload - foam package' system. © Published under licence by IOP Publishing Ltd.
