В работе использовали три компьютерных концепта стентоподобных опорных каркасов, созданных на основе анализа схожих баллонорасширяемых протезов. Моделирование выполнено в программе Abaqus/CAE, и включало анализ двух ключевых нагрузок, характерных для данного элемента: этапа сжатия и имплантации. В качестве модели материала использовали линейное описание кобальт-хрома, в качестве количественного критерия состоятельности концептов – напряжение по Мизесу и его качественное распределение на поверхности моделей в виде эпюр.</p></sec><sec><title>Результаты</title><p>Результаты. Анализ показал, что в двух из трех предложенных моделей возникают напряжения, превышающие предел прочности (933 МПа), – 999,6 и 954,0 МПа на этапе сжатия, достигающие 1022,4 и 1044,7 МПа соответственно на этапе имплантации. Концепт 3 обладал значительно меньшими напряжениями в ходе сжатия, однако в рабочем состоянии показатели приближались к пороговым, достигая 924,2 МПа.</p></sec><sec><title>Заключение</title><p>Заключение. Численное моделирование выявило неэффективность концептов 1 и 2 и направления для оптимизации концепта 3 – снижение амплитуд для формирования «запаса прочности» напряжения. Анализ подчеркнул важность численного моделирования в ранней оценке и оптимизации медицинских изделий.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: To perform a quantitative analysis of the effectiveness of three concepts of heart valve prosthesis support frames from the perspective of their safety under the most critical loads, conducted through numerical modeling.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. The study utilized three computer-generated concepts of stent-like support frames, created based on the analysis of similar balloon-expandable prostheses. The modeling was conducted using Abaqus/CAE software and included the analysis of two key loads characteristic for this element: compression and implantation phases. A linear description of cobalt-chromium was used as the material model. The feasibility of the concepts was quantitatively assessed using von Mises stress and its qualitative distribution on the surface of the models as stress contours.</p></sec><sec><title>Results</title><p>Results. The analysis revealed that two of the three proposed models experienced stresses exceeding the strength limit (933 MPa) – 999.6 and 954.0 MPa during the compression phase and reaching 1022.4 and 1044.7 MPa, respectively, during the implantation phase. Concept 3 had significantly lower stresses during loading; however, in the working state, the indicators approached the threshold, reaching 924.2 MPa.</p></sec><sec><title>Conclusion</title><p>Conclusion. Numerical modeling identified the inefficacy of concepts 1 and 2 and directions for optimizing concept 3 – reducing amplitudes to form a “strength reserve” for stress. The analysis emphasized the importance of numerical modeling in the early assessment and optimization of medical devices.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>протезирование клапана аорты</kwd><kwd>численное моделирование</kwd><kwd>метод конечных элементов</kwd><kwd>стент</kwd><kwd>напряжение по Мизесу</kwd></kwd-group><kwd-group xml:lang="en"><kwd>transcatheter aortic valve replacement</kwd><kwd>numerical modeling</kwd><kwd>finite element method</kwd><kwd>stent</kwd><kwd>von&#13;
