军用车辆车底爆炸(UBB)是当今战场上许多严重伤害的原因，然而，这些混乱事件对人体的影响还没有被很好地了解。这项研究的目的是在受控的实验室环境中复制UBB负载条件和调查乘员反应。除了更好地了解人类对高速率垂直负荷的反应外，该测试系列还旨在确定高速率损伤阈值。使用弗吉尼亚大学的奥德赛模拟爆炸试验台，在不同的加载条件下完成了10次全身验尸人体代用品(PMHS)测试。坐姿加速度291~738g/s，持续3ms以上；足掌加速度234~858g/s，持续时间3ms以上。测试后进行计算机断层扫描(CT)和尸检以确定损伤，并显示骨盆、腰椎、胸部和下肢联合损伤。本研究探讨了高垂直负荷下的骨盆和下肢损伤。
Military vehicle underbody blast (UBB) is the cause of many serious injuries in theatre today; however, the effects of these chaotic events on the human body are not well understood. The purpose of this research was to replicate both UBB loading conditions and investigate occupant response in a controlled laboratory setting. In addition to better understanding the response of the human to high rate vertical loading, this test series also aimed to identify high rate injury thresholds. Ten whole body post mortem human surrogate (PMHS) tests were completed using the University of Virginia's ODYSSEY simulated blast rig under a range of loading conditions. Seat pan accelerations ranged from 291 to 738 g's over 3 ms of positive phase duration, and foot pan accelerations from 234 to 858 g's over 3 ms of positive phase duration. Post-test computed tomography (CT) scans and necropsies were performed to determine injuries, and revealed a combination of pelvic, lumbar, thoracic, and lower extremity injuries. The research in this paper discusses pelvis and lower extremity injuries under high rate vertical loads.
