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: dynamic dependences and adequate spatial computer calculation models are developed, pictures of stress-strain state of the offered concepts for restoration of effective functioning of obsolete open freight wagons, materials of their analysis are received; developed theoretical provisions, methodological foundations and practical concepts for restoring the efficient operation of obsolete covered freight wagons. According to the results of the research, publications [10, 11, 23-27, 31, 32] were made. The results obtained during this stage of research are the basis for the successful solution of the tasks of the subsequent stages of the project. Product Description popup.authors Kara Serhii V.
