Reinforced hopper car structure |
摘要 |
A hopper car is described that is a thin shelled integrated structure having a roof and a pair of sidewalls. This structure is subject to longitudinal tensile and compressive loads, and to a partial internal vacuum during unloading. Local buckling phenomena and collapse due to the partial vacuum need to be resisted. The roof assembly has lateral stiffeners to maintain its profile, and a reinforced, roll formed longituding coaming.
