В настоящее время необходимость внутригородских перевозок пассажиров становится острее. В России и за рубежом автобусы и электробусы повышенной вместимости, среди которых сочленённые и двухэтажные, зарекомендовали себя с хорошей стороны и их эксплуатация широко распространена. Особенно важно это для городов, в которых отсутствует сеть скоростного транспорта. Как следствие, в таких городах нагрузка от пассажиропотока ложится на наземный транспорт, основным видом которого является автобус или электробус.</p><p>Целью исследования является повышение устойчивости движения сочленённого электробуса с задней толкающей секцией за счёт введения упругодемпфирующей связи в узле сочленения. Методология и методы. Использованы методы имитационного моделирования.</p><p>Результаты и научная новизна. Показано, что устойчивое движение сочленённого электробуса с задней ведущей осью может быть обеспечено путём введения упругодемпфирующей связи в сцепном устройстве. Коэффициент демпфирования должен быть переменным и зависящим от величины угла складывания секций электробуса. Предложена схема гидравлической системы для сцепки электробуса, состоящая из двух гидроцилиндров, гидроаккумулятора и золотниковых устройств, обеспечивающая создание упругодемпфирующей связи между секциями. Анализ дифференциальных уравнений движения передней секции показал, что её прямолинейное движение является неустойчивым. Для обеспечения устойчивости её движения в шарнирном сочленении электробуса необходимо создать упругий восстанавливающий момент, направленный против угла складывания секций. Криволинейное движение задней секции является устойчивым.</p><p>Практическая значимость. Установлено, что введение переменного дросселирования в системе складывания секций сочленённого электробуса с задней толкающей секцией повышает устойчивость его движения при совершении манёвра «поворот» на опорных поверхностях с низкими сцепными свойствами.</p></abstract><trans-abstract xml:lang="en"><p>Introduction (statement of the problem and relevance). Currently, the need for intra-city passenger transportation is becoming more acute. High-capacity and electric buses, including articulated and double-decker ones, have proven their efficiency both in Russia and abroad and are widespread. The fact is especially important for the cities that do not have a network of high-speed transport. As a result, in these cities the passenger traffic load falls on ground transport, the main type of which is a bus or an electric bus.</p><p>The purpose of the study was to increase the stability of an articulated electric bus with a rear pushing section in motion introducing an elastic-damping connection in the articulation unit.</p><p>Methodology and research methods. Simulation modeling methods were used.</p><p>Scientific novelty and results. It was shown that the stable movement of an articulated electric bus with a rear driving axle could be ensured by introducing an elastic-damping connection in the coupling device. The damping coefficient must be variable and dependent on the folding sections angle of the electric bus. A hydraulic system scheme for an electric bus coupling was proposed, consisting of two hydraulic cylinders, a hydraulic accumulator and spool devices, which ensured the creation of an elastic-damping connection between the sections. The differential equations analysis of the front section motion showed that its rectilinear motion was unstable. To ensure the stability of its movement in the electric bus articulation, it was necessary to create an elastic restoring moment directed against the folding sections angle. Curvilinear movement of the rear section was stable.</p><p>Practical significance. It has been established that the introduction of variable throttling in the sections folding system of an articulated electric bus with a rear pushing section increases the stability of its movement when making a “turn” maneuver on supporting surfaces with low grip properties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сочленённый электробус</kwd><kwd>устойчивость движения</kwd><kwd>сцепное устройство</kwd><kwd>упругодемпфирующая связь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>articulated electric bus</kwd><kwd>motion stability</kwd><kwd>coupling device</kwd><kwd>elastic-damping connection</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">Zhan W., Liu C., Chan C.-Y., Tomizuka M.
