Determining patterns in loading the body of a gondola with side wall cladding made from corrugated sheets under operating modes

The object of research is the processes emergence, perception, and redistribution loads in body a universal railroad gondola with cladding corrugated sheets. To improve strength sheets cladding, it proposed to strengthen most loaded area terms height (1/3 bottom tie-up) horizontal corrugations. Determination geometric parameters corrugation carried out by moment resistance sheet. dynamic load improved was determined mathematical modeling. fluctuations jump were taken into consideration, that is, translational movements relative vertical axis. results solution model have made possible conclude studied dynamics indicators are within permissible limits while car movement estimated as "excellent". calculation performed cladding. It has been established under main operating modes ensured. According calculations static strength, fatigue body. must be said increases 3.7 % compared typical one. A feature obtained improvement can not only at design stage but also during repairs cars. scope practical use includes engineering industry, particular transportation. At same time, conditions for application compliance requirements loading unloading operations current will contribute devising recommendations modern structures gondolas improving efficiency their operation.
