RESEARCH OF THE CONTOL SYSTEM OF THE PROPORTIONAL ELECTROHYDRAULIC DISTRIBUTOR

Анотація

There had been developed the mathematical model and the research of the control system for the proportional electro hydraulic Distributor were conducted. There had been conducted the simulating research of pressure distribution in the control system by COSMOS FLOWORKS software, on the basis of the research results there had been modernized the construction of the system, that allowed to increase the control pressure. There had been determined the limits of values of design parameters of control system, which ensure stable operation of the distributor. On the base of research upon the mathematical model there had been specified the dependence of the operation response of the control valve in the second cascade of the directional control valve on flow characteristics of throttle elements in the first cascade and operation response of the valve in the first cascade. There had been determined the aggregates of values in constructional parameters which ensure the maximum operation response in functioning of the valve in the first cascade and control valve in the second cascade of the directional control valve.
