The article presents the studies of the elastomeric isolator performance under static loads. The solutions of the problems have been obtained by means of a specialized software complex by direct integration of the motion equations according to the implicit scheme. For calculation of the elastomeric isolator, a 3D computational model comprised by solid finite elements has been used. Based on the results of the studies performed, the diagrams for displacement of the points of the top of the support have been plotted with the horizontal shear of the support. The possibility of formation of tilting in the upper plate of the elastomeric isolator has been proved. The diagram of residual horizontal displacements of the support after the horizontal load removal has been obtained. The inability of elastomeric isolators to return independently to the initial equilibrium position without additional devices has been proved.
