According to the experience of military conflicts in recent decades, including the Anti-Terrorist Operation (Joint Forces Operation), it is known that the survivability of armored combat vehicles and crew largely depends on the level of their protection. From the analysis of the received damages during performance of tasks it is known that repeatedly fighting armored cars due to a low level of protection lost a working condition because of receiving damages of knots (aggregates) by fragments of external armoring, which were formed during its penetration. Therefore, the task is to find ways to improve the layout of armored combat vehicles, to reduce the number of deadly fragments generated by external armor.

The article presents an approach for evaluating the results of the impact of fragments of external armor elements on the internal equipment of armored combat vehicles using mathematical modeling of the processes of spreading the action of fragments on the internal units of the vehicle. It was also found that the fragments, which have a high impact capacity, fly behind the obstacle in the form of cone-shaped flows and are evenly separated, and their penetrating ability is a random variable. Therefore, the article shows the probability of damage (penetration) of the aggregate by fragments, as well as the average number of fragments that can affect the aggregate.

For clarity, in accordance with the proposed method determined the probability of damage to the aggregates of some abstract sample of armored combat vehicle, the results allow us to judge the nature of the impact of fragments on various aggregates and combat calculation of armored combat vehicle, as well as identify those vital aggregates that are more subject to influence and damage by fragments.
