Blast Event Simulation for a Structure Subjected to a Landmine Explosion 2006-01-0931

One of the main threats to military vehicles originates from landmine blasts. In order to improve the survivability of the occupants it is important to design a military vehicle for increased occupant safety. Simulation technology that combines modeling of the blast loads from the landmine explosion, the response of the vehicle to the blast load, and the loads developed on the members of an occupant are important factors in this effort. The ability to simulate the landmine explosion is validated first by comparing simulation results to test data collected by gages placed in the ground and above the ground. Combined simulations predicting the damage to a target structure due to a landmine explosion are also compared to test data for further validation. Principal component analysis and metamodel theory is employed for generating fast running models in order to adjust the soil parameters in the simulation models during the correlation effort. Good correlation is demonstrated between the simulation methods and the test data. A case study is also performed in order to demonstrate how this new simulation technology can access the safety of an occupant due to the blast load applied on the hull of a military vehicle.
