FIELD: mechanical engineering. SUBSTANCE: device has housing 1, spring-loaded or elastic flexible member 3 of constant stiffness secured to housing 1 and to object from below, polarized electromagnet 4 whose armature 5 is secured to object 2; inductance coil 6 is secured to housing 1; magnetic portion of armature 5 is located inside inductance coil 6 so that end-piece of magnetic portion of armature 5 is below zone of permanent tractive force of electromagnet 4 (in initial position) by magnitude equal to sum of static compression of flexible member 3 under action of half mass of object 2 and maximum amplitude of vibrations of housing 1 or object 2; adjustable DC source 7 is connected to inductance coil and provides for drawing armature 5 into induction coil 6. Principle of operation of device is based on automatic maintenance of vector sum of reaction of flexible member 3, reaction of ppolarized electromagnet 4 and mass of object 2 at zero level at dynamic displacement of housing 1 relative to object 2 or vice versa. EFFECT: enhanced efficiency of vibration protection of object through stabilization of its bearing reaction and position in wide range of change of amplitudes and frequencies of vibrations of disturbance actions; enhanced reliability of device through simplification of its construction. 2 cl, 1 dwg |
