Design with rubber (elastomer) - metal elements (futter- RME) successfully used for the construction machine. Due to the continual development of machinery and equipment, are ever increasing in intensity and dynamic load requirements of the components of the relative position accuracy. Detail the relative position variation (such as radial, sharp and angular displacement transmission shafts, bearings sitting inaccuracies, delays threaded plugs, etc.) May result from deficiencies in the assembly, temperature changes and deformation forces, process constraints. To analyze the RME construction work need to know elastomer mechanical modules. In work it is offered to define factor of Poisson's ratio from experiments on axial compression of multilayered packages from thin-layer elastomer layer. To exclude influence of ruggedness of experimental installation on the indication of devices, it is offered to select number of layers in a package and geometrical parameters elastomer layers so that deposit of a layer at the expense of change of its form and compressibility elastomer, were one order. For processing of experimental data it is offered to use analytical decisions ("force-settlement") for a package from thin elastomer layers. The calculation example confirms applicability of the considered technique for definition of factor of Poisson's ratio for elastomer.
