shock wave - 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.
