Numerical Analysis
of the Mine Blast Action on an Armored Vehicle for Different V-hull
Geometries
Milica Glavšić
Predrag Elek
The main objective of
this research is to develop a numerical model of vehicle damage
caused by an explosion of a mine, as well as to find the most
favorable case of V-hull geometry and to point out a possible
solution for mitigating the effects of mine explosion on an armored
vehicle. Seven different V-hull geometries were considered and
structure damage analysis was performed for all seven options. Also,
the mass change for different geometries was analyzed. The effect of
the mine explosion on the target structure was analyzed using the
overpressure function according to the empirical CONWEP model, using
Abaqus / Explicit software. An example of an explosion of 8 kg of
Composition B acting on a vehicle with a total mass of 8000 kg was
analyzed. The vehicle has two main parts - the cabin with mass of 6
t and a V-hull of mass of 2 t. The V-shaped hull in all the examples
shown is made of 10 mm thick plates of Hardox 400 steel. The
position of the explosive charge is the same for all geometry
examples and is 0.6 m below the center of the vehicle. After
analysis of the obtained results the most favorable Vhull geometry
is determined. The guidelines for the further work and model
improvement are suggested.
