We present results and special features of the conducted experimental studies into proposed theory of implementation of the coupled design of a center girder of hopper wagons for iron ore pellets. The importance and relevance of the set scientific and practical task is predetermined by economic expediency. In particular, by the attained possibility of bringing down the cost of manufacturing such wagons by10 %. In addition, such approach could be used for the modernization (including scheduled repairs of different types) of wagons under study, which would make it possible to significantly reduce the cost of their operation.
The research found that the coupled design of the center girder of hopper wagons for iron ore pellets would guarantee to ensure the required indicators for operational reliability over the rated service life of wagon of 15 years. We can highlight as the scientific results of the work conducted the developed and experimentally-confirmed comprehensive technique for the implementation of coupled designs of wagon beams. The practical importance of research results is demonstrated by the proposed and patented solutions of technical realization of the chosen direction, implemented at a number of Ukrainian wagon building companies. The new and valuable results of present work include a created adequate spatial finite-element computer model of the improved design of hopper wagons for iron ore pellets.
The proposed methodical complex for reducing the manufacturing cost of hopper wagons for iron ore pellets by the conjugated design of their carrying beams is expedient for application in other types of freight wagons, as well as other means of transport engineeringReferences
