THE INVESTIGATION OF EFFICIENCY OF THE VIBROABSORBING COATINGS OF THE MECHANICAL STRUCTURES

The object of investigation: the vibro-absorbing coatings to be applied to the mechanical structures (constructions). The purpose of the work: the evaluation of influence of the structure parameters relative change to be conditioned by the coating, on the decrease of the structure vibration depending on the type of structure, the mode and frequency range of excitation, the development of the efficiency design methods. The dependence of the vibration characteristics on the relation of the dynamic and dissipative structure parameters has been obtained; the disperse equation of the curvilinear pipeline oscillations has been solved; the design method of the energy losses design of the cylindrical cover and natural constructions (pipelines, frames) has been offered and experimentally checked. The methods developed in the work allow to prognose the efficiency of the vibroabsorbing coatings, to be applied to the different structures, and to select the best coatings version depending on the conditions. The obtained results have been used in the methods and recommendations, given by the Institute for use in the CB and in the plants of the enterprise, were included in the monographs on the struggle against oscillations and noise. The comparative tests of the different coatings have been performed and the most effective have been recommended for useAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
