Computatational Assessment of Protective Capabilities of Vehicle Floor, Seat and Occupant Response under Shock Loads

Shock waves are High pressure & Energy carrying transport media, Often Military Vehicles are subject to these shock waves. A Numerical analysis of floor-plate Armox-500T, an armoured grade steel for vehicle floorplate and occupants in the event of mine detonation under the vehicle cabin with Dynamic Explicit Finite Element Code LS-DYNA software was carried out, the shock wave from the mine was modelled approximately using Conwep and the vehicle driver was represented by using a Hybrid III dummy. The simulations found details of the model which includes, the displacement, the velocity, the acceleration, variation in the energy of the cabin's floor-plate, the stress the overpressure and the response of the dummy, obtained results were compared to experimental Results for validation
