In many cases, you must be able to adjust the stiffness of a rubber shock absorber during use, depending on the mode of operation, the workload of the unit or for some other reason. In this paper we propose a model of a rubber shock absorber with adjustable stiffness and the method of calculation depending of type “force – settlement” for such a shock. The solution is obtained by the method of Ritsa using the principle of the minimum complete potential energy of deformation and direct methods using functional considered by V.Prager [1] and converted to weakly compressible materials. As an example, are reviewed by the method of calculation of a cylindrical rubber shock absorber with adjustable. The resulting dependence of type “force – settlement” for this shock absorber during axial compression.
