Приведена математическая формулировка структурной интенсивности, система численного моделирования осуществлена в программном пакете ANSYS, техника визуализации векторных полей потока энергии осуществлена в программном пакете HyperView. Рассмотрены случаи использования различных возбудителей гармонических колебаний (точечной силы и давления на несколько элементов) и применения различных коэффициентов поглощения колебаний структурой. Использование разработанной системы позволило визуализировать поля структурной интенсивности на глобальной поверхности и исследовать доминантные пути потока энергии. Structural intensity analysis вместе с техникой его визуализации представляет собой мощный инструмент для контроля над вибрацией и шумом.</p></abstract><trans-abstract xml:lang="en"><p>The numerical simulation system for structural intensity analysis and visualization to apply for FEM-models has presented. The mathematical formulation of the Structural Intensity has introduced, the numerical simulation system has implemented in ANSYS program software, the visualization technique of the vector fields of energy flow has realized in HyperView software. The intensity vectors, streamline map and energy distribution in shell-elements plate under excitation force are calculated and visualized to predict mechanical energy transmission. The cases with different excitations (point force and pressure) and different damping parameters have been studied. Using the system, the analysis was carried out to visualize structural intensity fields on the global shell-elements structure and to investigate dominant energy flow paths from harmonic excitation sources. The structural intensity analysis together with visualization techniques provides a powerful tool for vibration and noise control.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>structural intensity analysis</kwd><kwd>автомобиль</kwd><kwd>вибро-акустическое поведение</kwd><kwd>FEM-моделирование</kwd><kwd>шум и вибрация</kwd><kwd>надежность систем автомобиля</kwd><kwd>NVH</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Stoewer, T.
