In order to increase the stiffness anybody chassis in Wheeled Armoured Vehicle on impact of the shock wave, the space frame part in body shell was conducted. The aim of this action is to reduce deformation and damage as a result of the detonation of the mine or an Improvised Explosive Device (IED) under the vehicle. To verify the conducted modernization, numerical calculations of the system response to a blast wave effect were carried out. The mass of the detonated explosive was increased from 6 to 20 kg of TNT. An explosive material was detonated centrally under the vehicle front part according to NATO requirements [1, 2]. The results of the calculations allowed for a deformation assessment of the floor plate and its displacement before and after modernization. A model and numerical calculations were performed using the following software: CATIA, HyperMesh, LS-PrePost, LS-Dyna. CONWEP approach was used to describe an influence of a pressure wave on the structure.
