The Anti-vehicle Under-body Blast Injury Simulator is a device that accelerates a plate vertically upwards in order to replicate the rapid displacement of the floor of a vehicle being attacked by a mine. The first of its kind, built in 2010, has been used to carry out tests on cadaveric and surrogate lower limbs in order to assess the pathophysiology of mounted (in-vehicle) blast injury and evaluate protective strategies.
