摘要

Complete cycle of design and manufacturing of a new railway hopper car with fiberglass body and roof is presented. To optimize the car manufacturing a numerical modeling of the vacuum infusion process was realized. Structural design, original layups development, finite element analysis of the car body structure was performed for the normative load cases where the applied loads were ordered by railway regulations. Besides of these cases the impact full scale testing of the body as a part of the car was simulated via real dynamic contact interaction of the car body structure with the bulk cargo. The subcomponent specimens were tested under operating conditions to support the structural design and experimental verification of the developed FE models. Finally, correlation between the simulation and the full-scaled impact testing of the car body consisting carriage was obtained.
