Analytical Study of Random Oscillations of Vibration Protection Devices with an Elliptical Hysteresis Loop for Absorbing Harmful Energies by Non-Linear Mechanical Systems and their ElasticDamping Elements

The paper discusses the analysis of forced random oscillations of a non-linear mechanical system, namely a heavy drilling machine, taking into account the damping ability of the operator (human body) as a mechanical system and the elliptical hysteresis loop of the absorption of harmful energies by the elastic-damping element.
