Improved Commuter Rail Workstation Table Through Crash Energy Management, Trevor Ness, Brandon Baker
Mechanical Engineering
Workstation tables in commuter rail trains have been identified as an area for improving passenger safety during train collisions. The goal of this senior project was to create such a table using a composite sandwich structure designed to safely absorb energy. Testing of previous table designs was used to establish engineering specifications for the static loading, work surface durability, and impact performance requirements of the new table. Analytical and finite element models were used to analyze new concepts until a design was achieved that could meet all specifications. The tabletop developed consists of a crushable aluminum honeycomb core with fiberglass …
