The article presents the results of investigations of the strength of the supporting structure of the bodyopen-top wagon at shunting impacts taking into account the different speeds. Research literature on thesafety of wagon fleet during the manoeuvres showed that the speed of collision of the wagons in operationexceed the standard. This causes increased force loading bearing structures gondola body and damagingthem. Almost half of all injuries in new wagons occurs when the dissolution from the hills. The greatestpercentage of damages falls on the supporting structures of wagon bodies.With the aim of ensuring the strength of bodies of wagons during shunting impacts to meet theincreasing speeds of the improved load-bearing structures, by putting on the most loaded areas of the framereinforcing plates. The thickness of the lining is selected proceeding from the condition of ensuring thestrength. Calculation of the strength of the body of a wagon carried out using the finite element method.The results of the calculation of the strength of the body of the wagon with respect to the proposedactivities, allowed us to conclude about the feasibility of the technical solutions. In addition, proposedmeasures for improvement of the supporting structure body of a open-top wagon allow you to maintain thetechnical condition at the existing repair facilities.
