Magnetic shock absorber
The utility model relates to the means of vibration protection of objects in various fields of technology, in particular, in engineering and transport. The magnetic shock absorber contains a hollow cylindrical body, open on one side, a cover mounted on this side, through which a rod is passed, to which a piston in the form of a circular magnetic washer is attached. Another magnetic washer is installed on the blind end of the cylindrical cavity. Between the piston and the bottom magnetic washer there is located at intervals a series of identical magnetic washers facing each other with the same poles. In this device, the housing, the stem and the cover are made of ferromagnetic metal and thus form a magnetic core. Inside the case is placed a cylindrical liner of metal having a high specific electrical conductivity. The Eddy currents (Foucault currents) induced in it lead to additional braking of the depreciable object attached to the rod. The technical result is an increase in the damping effect of the magnetic damper.
RUDN University mathematician together with colleagues from India and France for the first time studied in detail the system of coexistence of three species of living creatures in the wild. The results help to understand what parameters determine the extinction andли survivalof species, and how the number of species changes in space and time.
RUDN University chemist with his colleagues from Portugal has developed two types of coating based on new coordination polymers with silver. Both compounds were successfully tested against four common pathogens.
RUDN researchers have created and tested a method for processing titanium dental implants. It turned out that theanoslos of graphene on the surface of titanium improve its interaction with stem cells,which are placed on the implant so that it better "takes root".Thanks to this method ofprocessing, stem cells are better kept on the surface, multiply and turn into the desired cells.
