SYNCHRONOUS HYDROMECHANICAL DRIVE OF MOBILE ACTUATOR AND ITS MATHEMATICAL MODEL

Abstract

A synchronous hydromechanical system of the mobile actuator is considered as an example of the brush drive system of the airport sweeper. It is proposed to equip the synchronous hydraulic machine drive with a throttle flow divider of not spool-type including a plunger actuator to ensure the proper operation of the hydraulic drive system in the wide-range ambient temperatures under the low response to the process fluid quality. The flow divider construction diagram is offered, its functional principle, basic design, and operational characteristics are considered. The mathematical model of the actuator drive system with the use of the functions of determining flow rates and the given rigidity of the hydromechanical elements developed on the basis of the elastic-dissipative state model to simplify considerably the description and study of the hydromechanical system is obtained. The use of the proposed mathematical model creates conditions for calculating the optimum parameters of the actuator drive system already at the design stage.
