Скорость вращения этого ротора существенно меньше, чем у горизонтально-осевых турбин и вертикально-осевых турбин типа Дарье. Однако он начинает вращаться уже при небольшой скорости потока, не требует дополнительных систем, обеспечивающих его переориентацию в случае изменения направления ветра, и развивает достаточно большой крутящий момент. Поэтому представляется целесообразным использовать его в качестве привода в различных механических или электромеханических системах. В данной работе рассматривается прямолинейное движение колесной тележки, приводимой в движение установленным на ней ротором Савониуса. Предполагается, что ветер составляет некоторый постоянный угол с прямой, вдоль которой движется тележка. Аэродинамическое воздействие на ротор описывается с помощью эмпирической модели, в рамках которой аэродинамические характеристики ротора (коэффициенты аэродинамического момента, силы лобового сопротивления и боковой силы) представляются в виде разложения в ряд Фурье по углу поворота ротора, причем коэффициенты этого ряда зависят от быстроходности (безразмерной угловой скорости) ротора. В дозвуковой аэродинамической трубе НИИ механики МГУ проведена серия экспериментов по определению аэродинамических характеристик ротора при разных скоростях набегающего потока и разных угловых скоростях ротора. На основе полученных экспериментальных данных предложены функции, приближенно описывающие зависимость указанных коэффициентов от быстроходности. Полученные зависимости использованы для исследования динамики тележки с ротором Савониуса. Построено осреднение системы уравнений движения по углу поворота ротора. Исследованы стационарные решения этой осредненной системы в зависимости от направления ветра. Показано, что при определенных значениях параметров в системе существуют два притягивающих режима, соответствующих движению в разные стороны. Проведено сопоставление поведения тележки в рамках полной системы уравнений движения и в рамках осредненной системы.</p></abstract><trans-abstract xml:lang="en"><p>Savonius rotor is one of relatively wide-spread type of wind turbines. The rotation rate of this rotor is considerably lower than that of horizontal axis wind turbines and Darrieus wind turbines. However, it starts rotating at small wind speeds, doesn’t require any additional devices to ensure its re-orientation in case of change of the wind direction, and generates a rather large torque. Therefore, it is suitable for use as a drive in different mechanical and electromechanical systems. In the present paper, dynamics of rectilinear motion of a wheeled cart is studied, which is driven by Savonius rotor installed on it. It is assumed that the wind makes a certain constant angle with the line, along which the cart moves. The aerodynamic load upon the rotor is described with an empirical model, in the context of which the aerodynamic characteristics (aerodynamic torque, drag and lateral force coefficients) are represented as Fourier series with respect to the rotor revolution angle, the coefficients of the series being functions of the rotor tip speed ratio (dimensionless angular speed). Experiments were performed in the subsonic wind tunnel of the Institute of Mechanics of Lomonosov Moscow State University intended to measure aerodynamic characteristics of the rotor at different wind speeds and rotor angular speeds. Based on experimental data, functions were proposed that approximately describe the dependence of the above mentioned coefficients upon the tip speed ratio. The obtained dependences were used for analysis of dynamics of the cart driven by the Savonius rotor. The equations of motion are averaged with respect to the angle of revolution of rotor. Steady solutions of this averaged system are studied. It is shown that, for certain values of parameters, there exist two attracting steady motions corresponding to different directions of the cart velocity. Cart dynamics in the context of the full system of equations of motion is compared with its dynamics in the context of the averaged system.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>динамика</kwd><kwd>ротор Савониуса</kwd><kwd>колесный экипаж</kwd><kwd>стационарные движения</kwd><kwd>математическая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dynamics</kwd><kwd>Savonius rotor</kwd><kwd>wheeled vehicle</kwd><kwd>steady motions</kwd><kwd>mathematical model</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной поддержке Российского фонда фундаментальных исследований (проект 19-31-90073).</funding-statement><funding-statement xml:lang="en">This work was supported by Russian Foundation for Basic Research (project #19-31-90073).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Roy S., Saha U.
