С ростом скоростей движения увеличиваются динамические нагрузки на токоприемник со стороны подвижного состава и повышается аэродинамическое воздействие, что приводит к увеличению разброса величины контактного нажатия, появлению отрывов полоза токоприемника от контактного провода, дугообразованию в контакте и повышенному износу контактных элементов. Перспективным направлением в решении этого вопроса является применение систем автоматического регулирования, позволяющих стабилизировать величину контактного нажатия. В статье рассмотрены особенности современных систем автоматического регулирования нажатия токоприемников, указаны их основные недостатки. Предложена новая схема автоматического регулирования нажатия токоприемника, отличающаяся повышенным быстродействием. Описана математическая модель токоприемника и приведены результаты расчета параметров быстродействующей системы регулирования, показывающие возможность ее применения с целью снижения разброса величины контактного нажатия токоприемника и повышения качества токосъема при высоких скоростях движения.</p></abstract><trans-abstract xml:lang="en"><p>One of the limiting factors in increasing train speeds on railway transport is the quality of current collection. With increasing operation speeds, the dynamic loads on the current collector from the rolling stock increase and the aerodynamic impact increases as well, which leads to an increase in the variation of the contact pressure, tearing off the current collector from the contact wire, arcing in contact and increased wear of the contact elements. A promising direction in addressing this issue is the use of automatic control systems, allowing to stabilize the amount of contact pressure. The article discusses the features of modern automatic control systems for pressing current collectors, its main disadvantages are indicated. Authors proposed new automatic control circuit for pressing a current collector, characterized by increased speed. A mathematical model of a current collector equipped with a high-speed automatic pressure control system is described. The results of the calculation of the parameters of the high-speed control system are presented, showing the possibility of its use in order to reduce the spread of the contact pressure of the current collector and improve the quality of the current collection at high speeds. Analysis of the characteristics of the transfer functions of the regulator shows that the application of the PI controller algorithm is effective for stabilizing the contact pressure. Since the rod length of the pneumatic cylinder is limited, the regulator is able to maintain pressure for a limited time, after which the rod must be returned to its original position. The speed of the rod is limited by the characteristics of the actuator (electric motor). These features cause a significant variation in system parameters, such as the time constant and the duration of maintaining a stable depression, depending on the values of the controller coefficients kp and ki, which should be set taking into account the parameters of the current collector, operating conditions and type of contact suspension. For the considered current collector model, the optimal values of the controller coefficients are kp = 1.5 and ki= 1.0. Results of the calculations showed that the use of a rapid regulator based on a pneumatic cylinder in the carriage design reduces the standard deviation of the contact pressure to 37 % at speeds of up to 260 km/h.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>высокоскоростное движение</kwd><kwd>токопри- емник</kwd><kwd>математическая модель</kwd><kwd>контактное нажатие</kwd><kwd>система автоматического регулирования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-speed operation</kwd><kwd>current collector</kwd><kwd>mathematical model</kwd><kwd>contact pressing</kwd><kwd>automatic control system</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">Ецков Т.
