Publisher's Synopsis
The research team conducted a project to repair cars for use in a full-scale train-to-train collision test with crash energy management systems. The two cars had been damaged in previous dynamic tests. Several components required replacement, and some required design modification. This report describes the damage to the cars from the tests, and the various actions needed to repair and modify the components. Some collision dynamics and finite element analyses were conducted in support of the modifications. The projectincluded fabrication and assistance in implementing the repairs.
