С этой целью предлагается применить комплексную методику определения допускаемых параметров несимметричного размещения грузов, основанную на сочетании критериев прочности несущих элементов вагонов, обеспечения нормативного уровня показателей динамических качеств и устойчивости движения груженого вагона. Приведен пример определения допускаемых параметров совместного поперечного и продольного смещения общего центра тяжести вагона, загруженного до номинальной грузоподъемности.</p></abstract><trans-abstract xml:lang="en"><p>Due to the presence in the operating fleet of freight cars with a base of over 10 m, as well as the practical impossibility of symmetrically placing loads with a weight corresponding to the nominal carrying capacity on open rolling stock, adjustments to the existing asymmetrical loading standards are necessary. To this end, it is proposed to apply a comprehensive methodology for determining the allowable parameters of asymmetrical placement of freights, based on a combination of strength criteria of the bearing elements of cars, ensuring the normative level of dynamic qualities and stability of the loaded car. The article provides an example of determining the permissible parameters of the joint lateral and longitudinal displacement of the total center of gravity of the car (ЦТгр°), loaded to the nominal capacity. According to the results of the studies to determine the allowable values of longitudinal and lateral displacement ЦТгр° with unbalanced placement within the loading platform of the car, including the presence of a joint displacement, it was found that to improve the efficiency of using freight cars with an increased base, it is advisable to update the current offset standards of ЦТгр°. It is recommended to take the values of longitudinal displacement ЦТгр° for cars with a body base of 14.6 and 19.0 m respectively 1.46 and 2.11 m for freight with a total weight of 50 tons; 1.10 and 1.43 m for freight with a total weight of 60 tons; 0.22 and 0.28 m – for freight with a total weight of 67 tons. When placing freights with a total weight of over 67 tons with a height of center of gravity of 2.0–2.2 m on 4-axle freight cars with an axle load of 230.5 kN without limiting the permissible driving speeds, it is recommended to use a graphical method for determining the joint (longitudinal and transverse) displacement ЦТгр°. With an increase in the joint displacement parameters ЦТгр°, it will be necessary to limit the speed of the car in the curved sections of the track and to the lateral direction on the turnouts.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>грузовой вагон</kwd><kwd>общий центр тяжести грузов</kwd><kwd>продольное и поперечное смещение общего центра тяжести грузов</kwd><kwd>статическая осевая нагрузка</kwd><kwd>коэффициенты динамических добавок</kwd><kwd>рамные силы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>freight car</kwd><kwd>general center of gravity of freight</kwd><kwd>longitudinal and transverse displacement of the common center of gravity of the freights</kwd><kwd>static axle load</kwd><kwd>coefficients of dynamic additions</kwd><kwd>frame forces</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">Технические условия размещения и крепления грузов: Приложение 3 к Соглашению о международном железнодорожном грузовом сообщении (СМГС): информационное письмо Минтранса России от 10.12.2014 г. № ОИ-05/5227. 112 с.
