Abstract

When a railway vehicle overturns in an accident, the carbody cross section is likely to take on a parallelogram shape as a result of side impact, and the survival space for passengers and crew is reduced as a result. To secure the survival space available, an innerring structure can be formed by uniting sub-frames attached to the inside of the carbody as non-structural members. The authors performed strength tests and FE analysis to verify the possibility of improving carbody strength against loads from the side by creating such a ring structure.
