| 摘要： | The Aircrew Biodynamics and Protection ABP Team of AFRL 711 HPWRHCPT and their in-house technical support contractor, Infoscitex, conducted an experimental effort involving a series of -X-axis and X Z-axis impact tests on the Horizontal Impulse Accelerator HIA. The purpose of the tests was to perform a comparative assessment of seat and torso mounted restraint systems during both horizontal and combined horizontal impacts. Parametric assessment was also conducted with other parameters including acceleration magnitude, headrest position relative to seatback tangent plane, and head supported mass helmet system. Overall, the series of comparative assessments indicated that a forward headrest of 2.5 relative to the seat back had minimal effect on the biodynamics response regardless of seat tilt position. The heavy helmet of 5 lb with a forward CG shift generated greater biodynamic responses for both the LOIS and the LARD manikin with the LOIS Nij and neck tension values exceeding the AFRL limits. |
