Abstract
This paper describes a study of crush behaviour of railway vehicle carbodies under side collision accidents. As the first step for evaluating the carbody side strength, the authors had previously performed static compression tests using full-size partial carbodies, and performed FE analyses in order to verify empirical results. In this paper, we describe the results of dynamic compression tests and FE analysis under the same condition as the tests. The numerical result by FE analysis was consistent with the empirical results in terms of the load-time characteristics as well as their deformed shape. We constructed a method for the evaluation of the impact deformation behavior against loads from the side by using FE analysis.
