The Influence the Location of Large Charge on Behaviour Special Vehicles SHIBA and AV (Armoured Vehicle)

The problem of impact resistance the vehicles is described in various articles and standardization documents. Mainly concerns on small size of explosive device. In the case of large charges like a 25 to 1000 kg, the literature of subject is very poor. Practically, when the mass of charge is over 1000 kg the level of security of vehicle do not have a sense. The energy emitted by 100kg charge is able to overturn and even lift up vehicle on weight up to 60 t. In the article present the influence of size the large explosive devices on behaviour the special vehicles. Was analyzed two special vehicles. One of them is vehicle to detection and neutralization the mines and improvised explosive devices. The second is armoured personnel carrier. In article presents the results of numerical analyses the mechanical system of vehicle – explosion, which is described by Euler fields and Lagrange elements. The interactions between vehicle and charge obtained by general coupling. Presents the results of numerical analyses for an elements the support structures of combat vehicle, which is loaded by impact generated by large explosive device.
