SOME RESULTS OF RESEARCH OF THICKNESS OF LAYER ON DAMPING CAPACITY OF THE THREE-LAYERED BEAMS
A general tendency in creation of modern machines and equipment a search and development of structural decisions of decline of vibration become created by their mechanisms. Their vibrations can be passed on frame and cabinet-type, and also fundamental constructions through the points of fastening. Indicated equipment are bound by much mass constructions, density of spectrum of vibrations of eigenfrequencies and variety of sources of excitation of vibrations are therefore inherent them. One of effective methods of decision of the indicated task is an increase of damping capacity of structural elements of the examined equipment due to application of new types or known materials with a high level dispersion of energy. Therefore the aim of the real work is a study of influence of sizes of intermediate layer and static pressure between layers on the damping capacity of the component stratified beams. For the study of influence of structurally-technological factors on a damping capacity component steel beams were used long a 1 m, consisting of two channels № 6,5, with layers from Viponit and Agat. On the basis of results of the conducted complex of experimental researches of beams, containing the layers of Vipont and Аgat, taking into account influence of thickness and static pressure between layers, it is possible to do such conclusions: a 1) damping capacity of component standards substantially depends on a thickness and type of layer, and also from static pressure between layers; 2) the level of damping of beams in dependence of type of layer can grow in 1,3.1,5 time; 3) the increase of static pressure in a beam in dependence of type of layer leads to the increase of level of damping of beams in 1,1.1,25 time.
