Ключевое направление в ее решении — увеличение пассажировместимости вагонов при обеспечении высокого уровня прочности, надежности и безопасности конструкции.</p><p>Представлена усовершенствованная конструкция кузова пассажирского вагона повышенной вместимости, разработанная с учетом современных требований к комфорту, экологичности и эксплуатационной эффективности. Для оценки характеристик конструкции был проведен комплексный анализ, включающий теоретические расчеты напряженно-деформированного состояния элементов кузова с использованием метода конечных элементов. Численное моделирование позволило выявить критические зоны конструкции и оптимизировать ее параметры для повышения прочности и снижения материалоемкости. Результаты моделирования были дополнены и подтверждены экспериментальными испытаниями опытного образца, проведенными в условиях, максимально приближенных к реальной эксплуатации.</p><p>Полученные данные свидетельствуют о соответствии конструкции требованиям действующих нормативных документов, включая стандарты безопасности и долговечности. Предложенная конструкция демонстрирует улучшенные эксплуатационные характеристики, что делает ее перспективной для применения в проектировании и модернизации пассажирских вагонов нового поколения. Результаты исследования могут служить основой для дальнейших разработок в области создания инновационного железнодорожного транспорта, обеспечивающего повышенный уровень комфорта и эффективности.</p></abstract><trans-abstract xml:lang="en"><p>In the context of the rapid growth of passenger traffic by rail, one of the priorities is to increase the efficiency of rolling stock use. The key direction in solving this problem is to increase the passenger capacity of railway coaches while ensuring a high level of their structural strength, reliability and safety. This study presents an improved design of the body of a passenger coach with increased capacity, developed taking into account modern requirements for comfort, environmental friendliness and operational efficiency. To assess the design characteristics, a comprehensive analysis was carried out, including theoretical calculations of the stress-strain state of the body elements using the finite element method. Numerical modeling made it possible to identify critical areas of the structure and optimize its parameters to increase strength and reduce material consumption. The simulation results were supplemented and confirmed by experimental tests of the prototype, conducted in conditions as close as possible to real operation. The data obtained indicate that the design meets the requirements of current regulatory documents, including safety and durability standards. The proposed design demonstrates improved operational characteristics, which makes it promising for use in the design and modernization of new-generation passenger coaches. The research results can serve as a basis for further developments in the field of innovative railway transport, providing an increased level of comfort and efficiency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пассажирский вагон</kwd><kwd>пассажировместимость</kwd><kwd>конструкция</kwd><kwd>рама</kwd><kwd>напряжения</kwd><kwd>прочность</kwd><kwd>испытания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>passenger railcar</kwd><kwd>passenger capacity</kwd><kwd>design</kwd><kwd>frame</kwd><kwd>stress</kwd><kwd>strength</kwd><kwd>testing</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">Бороненко Ю.П., Рахимов Р.В.
