Основная цель расчёта прочности – гарантировать безопасную работу котла при рабочих давлениях и температурах, предотвращая аварии, вызванные отказом материала или разрушением конструкции. Расчёт прочности позволяет определить оптимальную толщину стенок, распределение напряжений и прочность сварных соединений, чтобы избежать концентрации напряжений, деформаций и появления трещин. Расчёт прочности помогает выбрать наиболее подходящие материалы и толщину стенок, что позволяет снизить затраты на производство, сохранив при этом высокий уровень безопасности и надёжности конструкции.</p></abstract><trans-abstract xml:lang="en"><p>The primary objective of this study is to analyze the structural strength of a tank boiler using mechanical calculation methods and relevant standards to ensure its safety and reliability under operating pressures and conditions. The primary goal of the strength calculation is to ensure safe operation of the boiler at operating pressures and temperatures, preventing accidents caused by material failure or structural failure. Strength calculations help determine the optimal wall thickness, stress distribution, and weld strength to avoid stress concentration, deformation, and cracking. Strength calculations help select the most appropriate materials and wall thicknesses, reducing production costs while maintaining a high level of structural safety and reliability. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>цистерна-контейнер</kwd><kwd>прочность</kwd><kwd>транспорт</kwd><kwd>срок службы</kwd><kwd>оптимизация конструкции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tank container</kwd><kwd>strength</kwd><kwd>transport</kwd><kwd>service life</kwd><kwd>design optimization</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">ГОСТ Р. 34233.6-2017.
