MATHEMATICAL MODELING OF DYNAMIC PROCESSES IN THE HULL OF LIGHTLY ARMORED VEHICLE UNDER IMPULSIVE ACTION

Abstract

The paper describes the questions of modeling of dynamic processes in lightly armored vehicles. The studied object is associated with a parameter set that adequately describes battle module, armored hull and suspension as a dynamic system. The obtained set of variables completely identifies this dynamic system. It is proposed to carry out numerical modeling based on the integration of motion equations by the finite element method in order to determine the rational parameters. On the basis of analysis of researches results, parameters are determined that satisfy the relevant criteria and constraints. In particular, dangerous resonance modes are detected and the criteria for disabling from these regimes are formulated.

В работе описаны вопросы моделирования динамических процессов в легкобронированных машинах. С помощью метода параметрического моделирования исследуемый объект описан множеством варьируемых параметров, которые полностью идентифицируют динамическую систему "боевой модуль–бронекорпус–подвеска". Для определения рациональных параметров предложено проводить численное моделирование на основе интегрирования уравнений движения с помощью метода конечных элементов. На основе анализа результатов исследований определяются параметры, которые удовлетворяют соответствующим критериям и ограничениям. В частности, выявляются опасные резонансные режимы и формулируются критерии отстройки от этих режимов.

У роботі описані питання моделювання динамічних процесів у легкоброньованих машинах. За допомогою методу параметричного моделювання досліджуваний об’єкт описаний множиною варійованих параметрів, які повністю ідентифікують досліджувану динамічну систему "бойовий модуль – бронекорпус – підвіска". Для визначення раціональних параметрів запропоновано проводити чисельне моделювання на основі інтегрування рівнянь руху за допомогою методу скінченних елементів. На основі аналізу результатів досліджень визначаються параметри, які задовольняють відповідним критеріям та обмеженням. Зокрема, виявляються небезпечні резонансні режими та формулюються критерії відлаштування від цих режимів.
