Модели анализа реакции защитных экранов на действие кумулятивных боеприпасов

Abstract

В работе описаны базовые модели для анализа реакции защитных экранов на действие кумулятивных боеприпасов. С этой целью построены математические и тестовые численные модели механического взаимодействия боеприпаса в момент подлета к защитному экрану и в дальнейшем при взаимной деформации элементов созданной механической системы. Продемонстрировано влияние условий встречи боеприпаса с экраном на дальнейшее развитие сценария действия боеприпаса на бронепреграду. В частности, на примере решения тестовых задач исследовано влияние механических свойств материала решетчатого экрана и скорости встречи гранаты с экраном на разрушение элементов системы. На этой основе предложено создание виртуального испытательного стенда. Также на основе анализа полученных результатов предложено создать специализированную базу данных. The paper describes the basic models for analyzing of reaction of protective screens to the effect of cumulative ammunition. For this purpose mathematical and test numerical models are constructed for mechanical interaction of an ammunition at the moment of approach to protective screen and later in the mutual deformation of elements of the formed mechanical system. The influence of conditions of an ammunition meeting with the screen on the further development of the munitions action scenario on armor obstacles is demonstrated. In particular, the influence of mechanical properties of the grating screen material and the speed of grenade's meeting with the screen on the destruction of the elements of the system are studied using the example of test problems solving. On this basis, the creation of a virtual test stand is proposed. Also, based on the analysis of the results obtained, it is proposed to create a specialized database.
