Modelling of impact strength on combat vehicles

In the field of threads to tracked combat vehicle on these days battle field growing importance of wide range of mines. It concern both anti- tank mines - anti-bottom, anti-track, anti-side- as well as specially prepared explosives. In the paper were presented chosen fragment of carried out experimental tests of tank exposed to impact, caused by anti-bottom mine explosion, as well as results of that effect. Methodology how to build models of tested objects was presented. Models of objects that characteristics are similar to typical combat vehicles were tested and test results were linked to publish date and authors test results, then models were loaded. As a load was applied worked out and experimentally verified model of after blast wave propagation, generated by anti-bottom mine explosion, as result of after blast wave propagated in limited space. Conclusions contain information about abilities of presented test methodology. Obtained results of model testing confirm necessity and the possibility of shaping impact strength of armoured vehicles structures. Proper selection of shapes, geometric dimensions and general parameters of structural system may be one of the means to provide proper protection.
