At the present, the improvement of vibration isolation systems for equipment, machines and units remains an urgent task. The ways to solve this problem are based on the optimization of existing structures, the development and application of new vibration-insulating elements as well as the improvement of design methods. In particular, to ensure the reliable functioning of agricultural machines, units, working elements and other mechanization means for the technological processes of agricultural production one of the perspective areas is the use of hydraulic vibra-tion mounts in suspension systems for units. This type of mounts is used to mount engines, cabins of agricultural vehicles, and power units. This paper discusses the simu-lation of the dynamic behavior of a power unit attached to a fixed base by the hydraulic mounts. It is proposed to use approximating functions modelling real stiffness character-istics of the mounts. A comparative analysis with a similar design using rubber-metal mounts as vibration-insulating elements is presented.
