Non-linear large deformation crush analyses were conducted on a multi-level cab car typical of those in operation by the Southern California Regional Rail Authority (SCRRA) in California. The motivation for these analyses was a collision, which occurred in Placentia, CA, on April 23, 2002. The final deformed state of the leading cab car was unusual. This behavior contrasted with previous testing and analysis experience of single level equipment in collisions. This investigation explores the structural response of multi-level car structures. |
