Methodology for Establishing the Mine/IED Resistance Capacity of Vehicle Seats for Crew Protection
Abstract:
Many Army ground vehicles possess Structural characteristics that aim to improve the crew survivability when engaged by mine or Improvised Explosive Device IED. Increased ground clearance. a V-shaped underbody, or high curb weight cooperate to reduce acceleration effects to the crew. The seat, as a critical component of the overall mine blast protection solution, is often overlooked. as evident by the significant number of non-blast-resistant seats featured in army vehicles. Ten unique MRAP-1 candidate seat systems were obtained to evaluate their effectiveness at limiting vertical and lateral acceleration effects to the crew. Using vertical and horizontal shock machines and an instrumented THOR 50th percentile ATD. each seat was subjected to incremental vertical shock tests.
