Numerical Simulation and Optimization of an Off-Road Vehicle Floorboard for Mine Blast Damage Reduction

ABSTRACT: This paper studies numerically the response of V-shaped hull subjected to mine blast load using finite element analysis package ABAQUS. The V-shaped plates are made from Domex700 steel folded along the centre to provide different angles and a constant area of mm for each plate. Different masses of explosive are used to provide results ranging from large inelastic deformation of the plate to tearing. A general trend of increasing permanent mid-point de?ection is observed for an increase in charge mass at a constant stand-off distance. The results showed that smaller angles de?ect more blast energy resulting in lower mid-point plate de?ection.
