- Аннотация: Complete cycle of design and manufacturing of a new railway hopper car 19-5167 with fiberglass body and roof is presented. Structural design, original layups development, FE stress analysis, testing of coupons and subcomponent specimens, an optimization of the vacuum infusion manufacturing process were realized by "ApATech" company in collaboration with Skolkovo Institute Science and Technology for production of the fiberglass hopper car body. FE analysis of the car body structures has been performed for the normative load cases where the applied loads were ordered by the Russian railway regularities. Besides of these cases the impact full scale testing of the body as a part of the car has been simulated via real dynamic contact interaction of the car body structure with a bulk cargo where the structure was modeled by Lagrangian mesh and the bulk cargo was modeled by Eulerian one. The subcomponent specimens were tested under operating conditions to support the structural design and experimental verification of the FE models. To optimize the car manufacturing a numerical modeling of the vacuum infusion process has been realized as well.
