Representatives of the Department of Railway Transport East Ukrainian National University named after Volodymyr Dahl - Ph.D., senior lecturer and graduate student Catherine Kravchenko Maxim Kovtanets - received certificates and marks of honor winners of the annual award of the President of Ukraine for young scientists in 2012. Dahl scientists - the only representatives of universities and research institutions of Lugansk region included in the list of Fellows. According to the Decree of the President of Ukraine № 642/2012 «About awarding annual prizes of the President of Ukraine for young scientists in 2012", Catherine Kravchenko and Maxim Kovtanets were awarded prizes for a series of scientific papers "Development of new technical solutions and ways to improve the performance properties of locomotives." Works inventors chair rail transport DREAMS them. Dal devoted to finding ways of improving performance properties of complex locomotives. Specifically, Dahl researchers identified causes deterioration of traction and dynamic qualities of the locomotive in service, reducing traction wheels with rails on various parts of the road, created a framework for constructing and operating crew of traction rolling stock, improved mathematical model of the movement of sand in the "jet sandbox - rack ". Moreover, in their studies Ekaterina Kravchenko and Maxim Kovtanets outline new approaches regarding maximizing traction recruitment drive motors (TED) on locomotive wheel pairs considering the uneven redistribution of loads TED characteristics and different friction conditions specific wheelset. In general, the measures proposed in the cycle dalivtsyamy scientific papers, improve the speed of movement, economic and environmental efficiency of operation of rolling stock.
