The article presents the comparative studies results of the dynamic loading of the drilling rig drive of oil-producing equipment in case of the piston compressor rigid attachment to the support frame and on elastic shock absorbers. The values of vibration displacements and vibration accelerations on the compressor housing in the operating frequency range of the crankshaft were determined by experiments. The obtained results showed that the location of the compressor on the shock absorbers reduces the level of vibration loads. Free and forced oscillations of the compressor housing were determined by the finite element method using the ANSYS R22 program. The problem was solved as a volumetric one, using the final elements of Solid Tet 10 node 187. The developed models for solving this problem assumed both options for attaching the compressor to the support frame. By placing the compressor on the shock absorbers it became possible to significantly reduce the frequency of free oscillations. The use of shock absorbers in the compressor drive also made it possible to reduce the resonance value and bring it beyond the operating rotation frequences.
