Abstract

In recent years, there have been significant advancements in the development of new regulations aimed at ensuring the structural integrity of passenger rail car interiors, specifically their ability to withstand compression. These regulations have been adapting to accommodate the inclusion of rail equipment that conforms to alternative standards, with the ultimate goal of achieving safety levels. A crucial change in these regulations involves the shift from using traditional draft lines to applying proof loads along the collision load path. This adjustment requires passenger equipment designed with alternative methods to demonstrate their ability to withstand specific loading scenarios, particularly those designed to resist buckling loads. This article provides a comprehensive examination of this shift in regulations, focusing on the use of various innovative design enhancements of stiffened panel used in train roof using finite element method. These enhancements come in different configurations, including T-shaped and Hat Stiffeners, as well as a novel hybrid design combining elements of both T-shaped and Hat Stiffeners. Through a thorough analysis, the performance of these new stiffener designs is carefully evaluated, with the primary aim of determining how well they meet the strength criteria set by traditional equipment. The results of this study revealed distinct differences among various panel types. Notably, the T-Hat panel outperformed the others, demonstrating the highest resistance to buckling forces. This is highlighted by a substantial difference of approximately 67.5% when compared to the T-type panel and a significant 34.0% difference when compared to the Hat-type panel.
