The surfaces of congruent cross sections were first identified in a separate class by Professor I.I. Kotov. Circular, elliptical and parabolic cylinders are taken as the guiding surfaces, and circles and parabolas are taken as generating plane curves, which can be located in the plane of the generating curve of the guiding cylinder or in a plane parallel to its longitudinal axis. The introduction of a new independent parameter helped to solve the set geometric problems. The analytical formulas are presented in generalized form, so the shape of the flat generatrix curve can be arbitrary. Two types of surfaces are considered: 1) when the local axes of the generating curves remain parallel during their movement; 2) when these axes rotate. The resulting surfaces can be of interest to architects, or can find application in machine-building thin-walled structures or in the study of the trajectories of bodies during their oscillatory-translational motion.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Рассматриваются новые кинематические поверхности, которые можно отнести к классу поверхностей конгруэнтных сечений. Поверхности конгруэнтных сечений впервые были выделены в отдельный класс профессором И.И. Котовым. В качестве направляющей поверхности принимаются круговой, эллиптический и параболический цилиндры, а за образующие плоские кривые - окружности и параболы, которые могут быть расположены в плоскости образующей кривой направляющего цилиндра или в плоскости параллельной его продольной оси. Решению поставленных геометрических задач помогло введение нового независимого параметра. Формулы приведены в обобщенном виде, поэтому форма плоской образующей кривой может быть произвольной. Рассматриваются два типа поверхностей: когда местные оси образующих кривых остаются параллельными при движении и когда они поворачиваются. Полученные поверхности могут быть интересны архитекторам, найти применение в машиностроительных тонкостенных конструкциях или при изучении траекторий движения тел при их колебательно-поступательном движении.</p></trans-abstract><kwd-group xml:lang="en"><kwd>computer aided design</kwd><kwd>pendulum type surface</kwd><kwd>surface of congruent cross sections</kwd><kwd>helical movement</kwd><kwd>kinematic surface</kwd><kwd>free form architecture</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>компьютерное проектирование</kwd><kwd>поверхность маятникового типа</kwd><kwd>поверхность конгруэнтных сечений</kwd><kwd>винтовое движение</kwd><kwd>кинематическая поверхность</kwd><kwd>архитектура свободных форм</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Kotov I.I.
