Моделювання системи керування гідроприводу стріли фронтального навантажувача на базі гальмівного клапана

Abstract

The provided firmness and necessary static and dynamic characteristics of a hydraulic actuator of the wheel loader on the basis of imitating mathematical modeling. At the same time such tasks are developed and solved: visual inspection of schemes of hydraulic actuators, designs of brake valves is made; the scheme of a control system of an arrow hydraulic actuator with a multipurpose brake valve is developed; the settlement scheme and mathematical model of a control system of an arrow hydraulic actuator is constructed; conditions of firmness are certain and static and dynamic characteristics on the basis of mathematical modeling of transitional processes are calculated; the analysis of the influence of productivity and accuracy of machine technology at the cost of mechanical treatment; the necessary economic calculations and feasibility studies; developed measures for labor protection and life safety. Developed the graphical part.
