Numerical Modelling, Simulation and Validation of the SPS and PS Systems under 6 kg TNT Blast Shock Wave

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
