rod armour - Opis:
- During ongoing conflicts around the world, some of the most dangerous threats are rocket-propelled grenades. They are light, easy to use and cheap, and their penetration reaches 900 mm of armoured RHA steel. Therefore, in many experimental and numerical laboratories there are researches of different, in aspect of shape, dimensions and used material, types of rod armours protecting against such a threat carried out. This kind of research must be confirmed in the last part of design by appropriate field tests. However, at the beginning of the design process, it is important to find a fast method of testing the developed solutions in a manner, which allows us to observe and measure as many process parameters as possible. One of such tests is research with the use of simplified models built in an appropriate scale. Small dimensions and simple construction result in the fact that the cost of manufacturing of models is much lower, and time is shorter. Tests on the simplified models are also possible to be carried out in laboratory conditions, what reduces the costs and makes the measurements of physical properties easier. The article describes experimental investigations of the impact of a simplified missile with a shape charge jet head model into a thick plate and steel rods. The construction of a missile, the used equipment and apparatus as well as the proceedings of the experiment are presented. The paper provides information about the structure of FE model and both initial and boundary conditions of the examined system. The results of numerical analysis are presented and compared with the results from experimental tests.
