Abstract and keywords

Currently, the majority of Under Body Blast (UBB) test of vehicles is carried out according to STANAG 4569 with the use of 50th percentile male Anthropomorphic Test Device (ATD) Hybrid III and Dynamic Response Index (DRIz) criterion based on the acceleration profile. In practice, the soldiers often wear Personal Protection Equipment (PPE) increasing their weight, such as massive bulletproof vests. In the paper, the increase of the spine injury risk as a function of the actual occupant mass and the additional load of the torso was estimated for three types of the blast‐attenuating seats. Modification of the DRIz criterion values with respect to the occupant mass and additional inertial loading of the torso was proposed. Influence of PPE inertia was also investigated with the use of detailed numerical model of the ATD and blast‐attenuating seat.

Keywords: blast attenuating seat, spine injury, Personal Protection Equipment, Under Body Blast
