The work objective is to study a mathematical model of the syn-chronous hydromechanical brush actuator of the airdrome sweeper driven by two hydraulic motors based on the throttle flow divider of non-spool-type with plunger setters. The main task is to determine the effect of various design and operational data of a synchronous hydraulic drive of a mobile technological machine on its functional efficiency. A method of the theoretical research of an actuator mathematical model is used. The simula-tion of the brush synchronous hydro-drive system is based on the theory of the modified volume stiffness of the hydraulic system that allows simplify modeling and make a rapid analysis of the drive performance under study, considerably shortening the time-line of the study. The research results prove that the throttle flow divider of non-spool-type with the plunger regulating element allows providing the required properties of the synchronized system. The design parameters of the flow divider having an essential impact on the synchronous hydraulic system operation are recognized, and ways of its improvement are specified. The research results can be used in design and improvement of the synchronous hydromechanical drives of mobile technological machines.

Введение. В современном технологическом оборудовании и мобильных технологических машинах широко применя-ются гидравлические приводы. В связи с этим как у нас в стране, так и за рубежом серьезное внимание уделяется изучению и описанию процессов, протекающих в системах гидравлических приводов. Особый интерес представляют во-просы управления и автоматического регулирования в системах приводов [1–6]. Настоящее исследование посвящено изучению указанных процессов в тех случаях, когда необходимо обеспечить работу двух или более гидравлических двигателей, запитываемых от одного источника расхода рабочей жидкости — насоса, гидроаккумулятора и др.
