A Study on the Structural Strength of Railroad Car

초록

This study is an experimental research on using stainless steel car body structure for urban railway vehicles. The car body used in the experiment was made of stainless steel. To evaluate the structural characteristics and safety of the stainless car body. As a method to save energy and materials, studies on lightweight car structures have been conducted. Stainless steel was first used in the United States in manufacturing railway vehicles 70 years ago. In Japan, lightweight stainless car body is most commonly adopted in the railway vehicle industry, and in Korea, it is currently being manufactured in the metropolitan areas. To evaluate safety, tests on the strength of car body was conducted, targeting vehicles modified in structures and shapes, when standards on the performance test of urban railway vehicles were applied as load conditions of the test. The urban railway vehicle model for this study is a Commuter DC Electric Traction Vehicle, which corresponds to a large-sized electric motor unit.
