Abstract:

The Federal Railroad Administration (FRA) sponsored research conducted at the Volpe Center aimed to assess the safety equivalence of the passenger rail seat dynamic test requirements specified in the United States (US) APTA 1 and Great Britain (GB) GMRT 2 safety standards. In this study, Volpe Center researchers utilized finite element (FE) simulations to replicate crash tests with forward-facing commuter rail passenger seats and two Hybrid-III 50th percentile male (H3-50M) anthropomorphic test devices (ATDs). The researchers conducted this study to address questions on the safety equivalency of the crash pulses specified in the two safety standards and the different requirements for injury criteria. Notably, the APTA seat standard uses a triangular 8g crash pulse, while the GMRT safety standard uses a less-severe trapezoidal 5g crash pulse. It is noteworthy that despite the less severe crash pulse, the GMRT standard imposes more stringent requirements for injury criteria overall.
