- The article presents the issue of increasing the passive safety of soldiers in a military vehicle, which is subject to loads resulting from an explosion IED or mine. Traditional methods of increasing security involve the application of additional layers, which are made using materials with high density. This approach contributes to the reduction of mobility and efficiency of a vehicle on the battlefield. For these reasons, it is necessary to search for a new structural design, which will benefit from a solution, which will not worsen the driving parameters of a vehicle in combat. Therefore, we propose a novel solution of openwork panel with dividers. The effectiveness of the system will be checked by verified on the bench traverse. The blast shock wave will be induced by detonation of HE charge at the central point over 430 mm from the top surface of the range stand. Experimental test will be used to validate the numerical model. After positive validation and verification, numerical model it can be used for other blast conditions or optimize protective shield. The problem considered in the study was solved numerically with the FEM using the following CAD-CAE systems: CATIA (to prepare a surface model), HyperMesh (division into finite elements), LS-Dyna (a solver), LS-PrePost (pre and post processor).
