Aerospace Instrument-Making Annotation << Back The hydraulic drive with regulation of a working body stream direction. The flow equation and the generalized mathematical model of the power part of actuators S.L. Samsonovich The control technique of the electrohydraulic actuators in which step and speed changing is realized by regulation of a working body stream direction is considered. The equation of the working body flow is examined. The mathematical model of the power part of the actuator has been compiled. The analysis of the most effective utilization of the drive from the point of view power is carried out. The substantiation of mechanism parameter selection with high dynamic characteristics is introduced.
