Keywords: railway, buckling, impact strength, structural analysis, finite element method.

Summary

In recent years, extensive dynamic analysis and structural analysis has been done while considering abnormalities, such as derailment and collisions with foreign objects. In such situations, longitudinal force that exceeds design load may be applied to the car body. In this paper, the longitudinal strength of a railway vehicle, made in accordance with Japanese industrial standards (JIS), is evaluated in consideration of plastic deformation. As a result, it was clarified that existing vehicle structures have much larger longitudinal crippling strength than elastic strength as defined in the standards. In addition, this paper examines the effect that dynamics and load path have on longitudinal strength and the location of buckling.
