Army ground vehicles are continuously being enhanced to mitigate warfighter occupant injuries during severe vertical loading caused in an underbody blast event. Energy absorption from stroking seat is one of the commonly used design feature. In addition to this, another design feature that is increasingly being utilized is stroking floors. However, the effectiveness of a stroking seat when mounted on a stroking floor may depend on many parameters such as weights of seatfloor system, stiffness characteristics, payloads and the characteristics of the blast itself. This paper presents a comprehensive design analysis of such a stroking seat on stroking floor system and the optimal design points that can mitigate the occupant injury to a range of input parameters. One key conclusion from the study is that blast-mitigating seats must not be designed as isolated subsystems but with careful consideration of how they interact with other blast-mitigation design features as stroking floors.
