Abstract. The aim of this study was to develop a practical
solution that would effectively limit load transmission through the floor
of a vehicle experiencing a landmine explosion and thus help
to protect the lower limbs of the occupants. A false-floor
approach was proposed and a drop-test was used to examine
alternative false-floor configurations. The mechanical properties of the insertion materials
used in the false-floor were measured and explicit finite element
method (FEM) modeling then carried out to simulate the drop-tests.
Based on these tests and the FEM modeling results, a
practical false-floor configuration was proposed. Finally, explosive field trials were
conducted in which biofidelic surrogate legs were used. The results
confirmed that the proposed false-floor approach was an effective method
for limiting impact loads to the lower limbs.
