  <dc:description>A train running along a track is one of the most complicated dynamic and static systems in engineering due to having various nature of contacting wheel and rail. The railway vehicle structures generally have the main components of shells, center sill, under frame, and beams, and behavior of these members directly affects static and dynamic structural behaviors of these vehicles. The central structural design Requirements are given by the main static and dynamic loads. The purpose of the study is to model and analyze a rail vehicle carbody structure that solves the issue of strength and comfort. Modern rail vehicles passenger carbodies are designed as lightweight structures with the aim to minimize mass and thus operational energy demand. At the same time the vehicle carbody shall be designed as stiff as possible to withstand exceptional loads. The output of the analysis shows that the maximum deflection occurs at midway of the span of the length and the selected sections for the different components of the rail vehicle are capable of carrying the intended purpose. In addition, the first six natural frequencies are calculated using ANSYS design and modeling software. The frequency is compared to the sensitivity range of human being in vertical ride comfort. The design and analysis is became an input to Railway Corporation and local manufacturer"s that has plant to substitute import by local manufacturing of passenger rail vehicle car bodies</dc:description>
