Crush Analysis of Tilting Train Express M-Car Initial Design

In this paper, the crush characteristic of the tilting train express M-car was estimated under a head-on collision scenario. The car body was divided into three parts - front, middle, and rear. For each part, crush-force relation was evaluated numerically using LS-DYNA 3-diementional shell element analysis. This result will be used for one-dimensional collision analysis of the full train rake.
