実物大のステンレス鋼製鉄道車体構造を用いた衝突試験

抄録

The crash safety structure of the railway vehicles is important as one of the safety measures against the train crews and the passengers in the event of a collision accident. It is impractical to perform collision testing many times using the actual train unit in order to design the crash safety structure. Therefore, the numerical simulation is effective and it is important to validate the analytical accuracy. Firstly, the authors performed the impact test using an actual-size partial stainless-steel carbody structure of a railway leading vehicle for the purpose of validating and improving the analytical accuracy of numerical simulation. Secondly, we carried out finite element analysis under the same condition as the experimental test. We compared the numerical result to the experimental one in terms of each compression loads measured by 6 load cells and the time history of velocity of test specimen. As a result, the numerical result was consistent with the experimental result.
