dc.description.abstract | Osnovni cilj ovog istraživanja je izrada numeričkog modela oštećenja vozila pod dejstvom eksplozije mine, kao i pronalaženje najpovoljnijeg slučaja geometrije V-trupa i ukazivanje na moguće rešenje za ublažavanje efekata eksplozije mina na oklopno borbeno vozilo. U obzir je uzeto sedam različitih geometrija V-trupa i izvršena je analiza oštećenja strukture za svih sedam mogućnosti. Takođe, analizirana je i promena mase za različite geometrije. Efekat eksplozije mina na ciljnu strukturu analiziran je korišćenjem funkcije natpritiska prema empirijskom modelu CONWEP, korišćenjem programa Abaqus/Explicit. Analiziran je primer eksplozije 8 kg eksplozivne materije Kompozicija B koja deluje na vozilo ukupne mase 8000 kg. Vozilo se sastoji od dva glavna dela - kabine mase 6 t i V-trupa mase 2 t. Trup u obliku slova V je u svim prikazanim primerima sačinjen od ploča debljine 10 mm izrađenih od čelika Hardox 400. Položaj eksplozivnog punjenja je za sve primere geometrije isti i nalazi se 0.6 m ispod centra vozila. Nakon analize dobijenih rezultata utvrđena je najpovoljnija geometrija V-trupa i ukazano je na mogućnosti daljeg unapređenja numeričkog modela. | sr |
dc.description.abstract | The main objective of this research is to develop a numerical model of vehicle damage caused by an explosion of a mine, as well as to find the most favorable case of V-hull geometry and to point out a possible solution for mitigating the effects of mine explosion on an armored vehicle. Seven different V-hull geometries were considered and structure damage analysis was performed for all seven options. Also, the mass change for different geometries was analyzed. The effect of the mine explosion on the target structure was analyzed using the overpressure function according to the empirical CONWEP model, using Abaqus / Explicit software. An example of an explosion of 8 kg of Composition B acting on a vehicle with a total mass of 8000 kg was analyzed. The vehicle has two main parts - the cabin with mass of 6 t and a V-hull of mass of 2 t. The V-shaped hull in all the examples shown is made of 10 mm thick plates of Hardox 400 steel. The position of the explosive charge is the same for all geometry examples and is 0.6 m below the center of the vehicle. After analysis of the obtained results the most favorable V-hull geometry is determined. The guidelines for the further work and model improvement are suggested. | en |
