Оптимізація конструктивних параметрів гідророзподільника для гідроприводів, чутливих до навантаження мобільних робочих машин

Abstract

Load-sensing (LS) hydraulic drives have considerable better characteristics than traditional hydraulic drives. In order to the designed directional control valve a mathematical model has been developed. The optimization criterion of the directional control valve of LS hydraulic drive has been developed. It includes bath static and dynamic characteristics. According to the stated optimization parameters optimal design parameters combinations of the directional control valve of LS hydraulic drive have been found.
