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) modelling then carried out to simulate the drop-tests. Based on these tests and the FEM modelling 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.
