Description	Research of vibration-isolation system with gyroscopic stabilizer is based on the research of vibration-isolation of lying human body during transportation. During the previous research there was designed the three-degree of freedom vibration-isolation system - one vertical translation and two rotations around transversal and longitudinal axes. Vertical translation is conducted by paralelogram mechanism or scissors mechanism; rotations are conducted by gimbals (Cardan suspension). We have suggested extending this system by twoaxis gyroscopic stabilizer with power gyroscopes. The power gyroscopes with sufficient magnitude of angular momentum move the natural frequencies (without gyroscopic stabilizer approximately 1-5Hz) of gimbals frames into the higher values (nutation frequency) and precession motion of gyroscopes is slow or aperiodic. Thus it means that the natural frequencies of gimbals, which previously have been located into the band of excitation signals spectra, have been moved outside this band. The paper describes suggested solution of the lying human body vibration-isolation and its mathematical models. There is also described the optimization of the systems of radial corrections. There is introduced the new solution of the compensation drive – based on the control of pneumatic springs. And also there are discussed some aspects of hard nonlinearities effects on the behaviour of described mechanical (or mechatronic) system.
