Determining loading patterns in the bearing structure of a railroad flatcar with a floor made from sandwich panels

The object of research is the processes emergence, perception, and redistribution loads in supporting structure a flatcar with floor made sandwich panels. To reduce impact dynamic on flatcar, as well safety goods transported it, it proposed to manufacture floors from Within framework study, mathematical modeling load when runs loaded state was carried out. It found that, taking into account solution, accelerations acting are reduced by 8.4 % compared typical one. At same time, cargo placed flatbed car 11.7 %. results calculating strength panels, arranged proved feasibility improvement. main indicators dynamics improved operated an empty were determined. established that movement assessed "good". A feature reported here contributes not only reducing its but also improving cargoes. scope practical application engineering industry, particular, railroad transport. condition for use energy-absorbing material study could contribute devising recommendations regarding design modern structures vehicles increasing efficiency functioning transportation industry
