FIELD: engineering.
SUBSTANCE: invention relates to mechanical engineering. Combined vibration isolation system contains a base, a spatial transmission mechanism, a pivot linking the base and a vibration-insulated object. Transmission mechanism is made in the form of two torsions in parallel mounted on the vibration-insulated object in hinges with oppositely attached levers at their ends. Free ends of the levers are connected with vertical rods by means of spherical hinges. Rods are connected to the base by spherical hinges. Three shock-absorbing springs are installed and fixed between the base of the vibration-insulated object and the base of the protected inter-floor overlapping of the building.
EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
