Railroad Seat Testing

Project Description

In August of 2003, the HSR-45 study was approved by the High-Speed Rail-IDEA Program Committee to analyze, design, and test a new type of crash energy absorption method for railcar passenger seats. This new energy absorption method would employ the solid ejection material (SEM) shock technology. Until the time of the HSR-45 study, SEM shocks had not been tested in low-impact load events, such as those experienced by unbelted passengers hitting their forward seats; instead the SEM technology had only been tested in large-scale crash absorption applications (e.g., low-speed bumper shocks on full-sized pickup, high-speed highway impact barriers).
