Для оцінки відносних властивостей захисного екрана до уражаючої енергії засобів ураження було проведено експериментальне дослідження, яке дозволило перевірити гіпотезу щодо захисту бойових броньованих машин від засобів ураження, на які діє кінетична енергія, засобів ураження. На підставі даних, отриманих під час експериментального дослідження, була побудована математична модель, яка описує імпульс удару ударника у захисний екран. Використання цієї моделі дає можливість розрахувати втрати енергії викликаної деформацією та руйнуванням перешкоди. Побудований в результаті багатофакторного експерименту математична модель описує вплив засобів ураження на захисний екран із врахуванням швидкості засобів ураження, кута нахилу захисного екрану, товщини переднього і заднього шару і твердості засобів ураження.
In order to evaluate the relative properties of the protective screen to the striking energy of the means of defeat, an experimental study was conducted, which allowed to test the hypothesis regarding the protection of the combat armoured vehicles against the means of defeat which, under the action of kinetic energy, destroy the armoured obstacle. Based on the data obtained during the experimental study, a mathematical model was constructed that describes the punching momentum of the protective screen. The use of this model makes it possible to calculate the energy losses caused by deformation and destruction of the obstacle. Built as a result of the multifactor experiment, the regularity of the impact of the means of defeat on the protective screen takes into account the speed of the means of defeat, the angle of encounter of the means of defeat with the protective screen, the thickness of the front and back layer and the hardness of the means of defeat.
