鉄道車両逸脱防止装置の耐衝撃性能評価に関する解析的研究

抄録

Recently, the risk of derailment accident caused by over-speed, earthquake and the other reasons is concerned. If bullet trains derail and collide against structures such as tunnel and building at high-speed, the unimaginable catastrophic accident will occur. Thus, as one of the effective measure for safety, the steel derailment stopper is proposed. But the collision phenomenon between a rotating wheel and steel derailment stopper could be extremely complex problem. From these backgrounds, this study aims at evaluating crashworthiness of steel derailment stopper by using 3-D elasto-plastic FE analysis. From the results of this study, it is confirmed how much train velocity and incident angle would affect critically crashworthiness of derailment stopper.
