Abstract

Analytical and experimental research stiffness characteristics of laminated packet are presented in this work. Package consists of alternating thin elastomeric and metallic layers jointed by vulcanization or gluing. Such packages are used in machine building, shipbuilding, civil engineering as compensating devices. The analytical expression of “compressive force – displacement” dependence is derived for the flat thin layered rubber – metal element on the basis of the variational principle; force is directed flatwise. The analytical expression of “shear force – deformation” is derived for the pre-compressed rubber-metal element. Analytical solution was confirmed by experimental data for flat packet in the shape of rectangular prism.
