The purpose of the project is to create theoretical provisions, methodological bases and practical means to restore the effective functioning of morally (models of samples of the seventies of the last century) and / or physically (operated on the verge of service life) obsolete structures of freight wagons, of which more than 70% domestic freight fleet. Research methods –methods of theory of development of technical systems and solution of inventive problems; methods of computer-mathematical modeling; finite element method; research methods of modern vehicles; methods for determining the dynamics and strength of machines. The following scientific and practical results were obtained: the results of experimental evaluations of typical designs of domestic freight wagons taking into account operational wear; developed and analyzed the dynamic dependences of the functioning of standard structures of freight wagons of the domestic fleet, taking into account operational wear; adequate spatial computer calculation models have been developed and pictures of the stress-strain state of the structures of freight wagons of the domestic park have been obtained, taking into account operational wear and tear, the results of their analysis; adequate spatial computer calculation models have been developed and pictures of the stress-strain state of freight wagons of the domestic fleet have been obtained, taking into account operational wear and tear, the results of their analysis; conceptual bases of improvement of obsolete open freight wagons are developed, namely: concepts for restoration of gondola wagons, platform wagons, hopper wagons by pushing the European Y25 type trucks; concepts for restoration of gondola wagons by: installation of fan-shaped vertical sheets in a pivot beam, installation on Product Description popup.authors Kara Serhii V.
