Abstract: A system reducing blast induced vehicle floor oscillation has a hull with brackets whose shoulders face edges of the vehicle sidewalls. The hull has a first position where the shoulders form a vertical gap with these edges and a second, risen position where the shoulders hit the edges. The brackets are connected to the sidewalls so as to permit rise of the brackets and V hull when a blast occurs but hold the V hull in the first position during normal vehicle use. Mounts on the vehicle frame are compressible by a vertical distance and support the cab. Rods of the hull are at another vertical distance from the frame. The sum of the vertical distances is equal to the vertical gap. When a blast occurs, the V hull's rise creates separate force paths from the hull to the floor to reduce floor oscillation.

Abstract: A vehicle occupant blast isolation system uses small explosive charges and small rocket motors to isolate vehicle occupants from blast loads. The system initiates the explosive charges to remove all mechanical linkages between the occupants and the initial shock so that no shock effects are transferred. The system counteracts the effects of the impulse by igniting the rocket motors to provide a restoring force to counter the effects of the impulse load. This combination of mechanical isolation and impulse negation addresses both the high-frequency initial shock and low-frequency impulse effects from explosive devices.
