KEYWORDS: workstation table; quasi-static testing; crash energy management; full-scale test; finite element analysis
This research effort is focused on providing a workstation table design that will reduce the risk of occupant injuries due to secondary impacts and to compartmentalize the occupants to prevent impacts with other objects and/or passengers seated across from them. The table must be capable of protecting the passengers in a seating arrangement with the table located between facing seats. Included in this study are the design, fabrication, quasi-static testing, and delivery of the table for subsequent testing in the crash energy management (CEM) full-scale test. Finite element analyses of the table components and multibody dynamic analyses of the occupant response were performed to help guide the design and predict whether the occupant injury risk for the newly designed table meets the requirements. Four tables were fabricated; two were included in the CEM full-scale train-to-train test in March 2006, and two were constructed for use in quasi-static and dynamic sled tests. To date, only the quasi-static tests and the CEM full-scale test have been performed.
