Results of a successful effort to significantly improve resistance of the tactical wheeled vehicle to mine detonation are reported. The design methodology is based on a comprehensive use of numerical simulation for blast/structure interaction and structure deformation as a result of blast load. Both Computational Fluid and Structural Dynamic (CFD and CSD) simulations are performed in three dimensions for the most comprehensive representation of the tactical wheeled vehicle geometry. Detailed three dimensional simulations of interaction of the blast waves generated by mine detonations against full configurations of tactical wheeled vehicles were validated by dedicated experiments. Three main scenarios for mine detonation were considered: command detonation of a mine under the truck crew cab, detonation of the mine under the front wheel, and detonation under the middle or aft wheel. Blast deflectors, designed using this comprehensive CFD/CSD methodology, were built and tested for blast loads generated by high explosive detonations. Results of these tests demonstrate a remarkable level of blast protection achieved by low cost deflectors of very simple geometry placed in key locations. The study demonstrates the advantages of including high level CFD/CSD simulations in blast deflectors design.
