Opis:: The paper presents the efficiency analysis of the passive shield which is opaque lightweight steel shell made of perforated panels arranged on the outer side of the building. The simplified calculation methodology is given. It is shown that the use of the shield lowers the outer temperature of the wall by several degrees which results in limiting heat gains in the summer, correspondingly.

Opis:: The paper develops a new methodology of FE modelling and simulation of the SPS and SP systems under 6 kg TNT blast shock wave. SPS code refers to the range stand – protected plate – protective shield ALF system, while PS code refers to the range stand – protected plate system. The multiple – use portable range stand for testing protective shields against blast loadings was developed under Research and Development Project No. O 0062 R00 06. System SPS uses high strength M20 erection bolts to connect the protective shield to the protected plate. In reference to the SPS system, validation explosion test was performed. It has pointed out that the developed methodology of numerical modelling and simulation of SPS and PS systems, using CATIA , HyperMesh, LS-Dyna, and LS-PrePost software, is correct and the ALF protective shield panels have increased blast resistance and high energy – absorption capability

Tytuł:: Explosive charge impact on the openwork steel shield
Autorzy:: Sławiński, G.

Opis:: 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).

Opis:: An article describes an issue of increasing the passive safety of soldiers in a military vehicle subjected to loads resulting from explosion mine or IED. Traditional methods to increase security involving the application of additional layers made using materials with high density. This approach contributes to a reduction mobility and efficiency vehicle on the battlefield. For these reasons, it is necessary to search new design solution, which will benefit low-density material through which driving parameters of vehicle in combat do not worsen. Mentioned reasons led to propose a new concept protective shield made of elastomer with inclusion in form of a liquid. Effectiveness of the proposed protective shield will be 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 tests 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. FEM numerical modelling, dynamic simulations and postprocessing were carried out using the following CAE systems: CATIA, HyperMesh, LS-DYNA (a solver), LS-PrePost.
