Симметричные нагрузки вызывают подпрыгивание,  а кососимметричные – галопирование. В статье анализируются влияния колебаний  подпрыгивания и галопирования кузова вагона на характеристики, определяющие безопасность  движения подвижного состава,  и дана методика такого анализа. При этом колебания подпрыгивания и галопирования рассматриваются  применительно к различным  линейным и инерционным параметрам кузовов вагонов. Исследование ведется для более точного выбора характеристик рессорного подвешивания вагонной конструкции.</p></abstract><trans-abstract xml:lang="en"><p>While the rail car is moving, the disturbing forces applied to the reinforcement points of the body are also changing. Thus the symmetric load causes bouncing, and antisymmetric load causes rocking. The authors have studied the impact of oscillations of bouncing and rocking of the car body on the features which predetermine safety of the rolling stock traffic and substantiated the methods of such analysis. The oscillations of bouncing and rocking are considered referring to different linear and inertial parameters of the cars’ bodies. The authors undertake an attempt to study and assess the existing differences in linear accelerations in order to better select the features of springing of the car body.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рельсовый путь</kwd><kwd>вагон</kwd><kwd>ходовая часть</kwd><kwd>опорные точки кузова</kwd><kwd>линейные ускорения</kwd><kwd>подпрыгивание</kwd><kwd>галопирование</kwd><kwd>рессорное подвешивание</kwd><kwd>динамические зависимости</kwd></kwd-group><kwd-group xml:lang="en"><kwd>track</kwd><kwd>rail car</kwd><kwd>moving parts</kwd><kwd>car body reinforcement points</kwd><kwd>linear accelerations</kwd><kwd>bouncing</kwd><kwd>galloping</kwd><kwd>rocking</kwd><kwd>springing</kwd><kwd>dynamic dependencies</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">ВершинскийС.В., ДаниловВ.
