Abstract. The researches carried out and calculated parameters of the stress-strain state of rubber vibroisolation supports for mining machines to increase their reliability and durability. As a result of experimental researches the dependence of the vibroisolating of support type VR201 upset from the magnitude of the axial-on loading. The results of calculation of stress-strain state of vibration support, based on the classical approach and the torque finite element method. Presents the distribution of the field of displacements and stresses in the fragment viboisolation support during its loading. The results can be used to select the permissible loading conditions when operating the test supports as part of vibration mining machines. The data on the heat generation in rubber elements type VR201 during long-enforcement cyclic loads on the basis of which the loading modes can be recommended to ensure the required reliability and durability of mining machines elements.
Keywords: vibroisolation support, mining machines, cyclic loading, stress-strain state, durability and reliability.
