Abstract

The issue of accelerated creation of efficient and energy-saving hydraulic drive of stem forage separator from trench storages by simulation modeling of technical systems. It is noted that the use of simulation allows to avoid significant investments required for the manufacture of a prototype of an agricultural machine, provided a detailed study physical model of the hydraulic drive of the stem feed separator. And also allows you to check the adequacy of the results obtained in process of mathematical modeling, and determine the necessary improvement of the proposed hydraulic drive. A fundamentally new constructive-technological scheme is presented stem feed separator from trench storage that allows to carry out process of unloading of a stalk forage from trench storages according to zootechnical requirements. The stand for simulation modeling of transients in the hydraulic drive of the stem forage separator from trench storages is offered. The design of the experimental stand also allows to investigate the hydraulic drive of the stem feed separator in the dynamic mode, when changing the technological load on the working bodies and changing the parameters of the adaptive fluid flow separator and the system in general. As a result of research and analysis of transients in the hydraulic drive, a fairly close coincidence of the results of mathematical and simulation modeling of the hydraulic drive of the stem feed separator, which allows us to recommend obtaining the calculated dependencies for use in the development hydraulic drives of stem feed separators.
