FIELD: nuclear industry; nuclear technology. ^ SUBSTANCE: the invention is pertaining to the nuclear technology and may be used by the works of separation of the radioactive and the stable isotopes arranged in the zones with seismic activity. The industrial group of the gaseous centrifugal machines is consists of the range of columns 1, mounted on the foundation 2, connected by the frame girders 3 with tiers of cantilevers 4, on which there are the aggregates of the gaseous centrifugal machines 5 mounted in height in several tiers. Above the frame girders 3 one or several slabs 8 are installed, each of which is fixed on the upper ends of the resilient rods 6 and 7 of different length and with the different resultant moments of inertia of the cross section. The lower ends of the rods 6 and 7 are fixed on the adjoining columns 1. Between the slab 8 and the frame girders 3 there is the mounted damping component 9 made in the form of a damper of the viscous or a dry friction fixed on the plank 13 by the screw bolts 20. The damper of a dry friction is made in the form of the spring-loaded shoe mounted in the fixed on the frame girder 3 body with the helical spring pressed by the washer and the adjusting screw. The ends of the resilient rods 6 and 7 are fixed on the plates 11 pressed to the columns 1 by the tightening device 12. On the slab 8 there is a mounted limiter 10, and on the upper end of the shoe there is the resilient ring, for example, made out of rubber. The design of the industrial group of the gaseous centrifugal machines reduces the factor of amplification of the seismic actions on the upper tiers of the arrangement and improves reliability of the equipment and at that does not require the complex design changes as compared with the existing version of the arrangement. ^ EFFECT: the invention ensures reduction of the factor of amplification of the seismic actions on the upper tiers of the arrangement, improves reliability of the equipment, does not require the complex design changes as compared with the existing version of the arrangement. ^ 14 cl, 3 dwg |
