Гидравлический привод суппорта станка с числовым программным управлением

Abstract

Данная выпускная квалификационная работа освещает вопросы связанные с проектированием системы автоматического управления, включающей гидравлический привод с дроссельным управлением, гидромотор. В работе произведен выбор основного оборудования силовой части системы (насоса и гидромоторов). Были рассчитаны элементы управления силовой частью привода и построены статические характеристики гидравлических устройств. По результатам расчетов был выполнен сборочный чертеж гидроусилителя типа «сопло-заслонка». В ходе выполнения динамического расчета электрогидравлической следящей системы получены передаточные функции и построены логарифмические характеристики разомкнутого контура исходной системы. Разработана структурно-динамическая схема системы автоматического управления. Была выполнена коррекция электрогидравлической системы управления последовательным способом. По ее результатам были построены обновленные логарифмические характеристики, выполнен анализ переходного процесса в системе автоматического управления.

This final qualification work highlights issues related to the design of an automatic control system, including a hydraulic drive with throttle control, a hydraulic motor. In the work, the main equipment of the power unit of the system (pump and hydraulic motors) has been selected. The controls for the power part of the drive were calculated and the static characteristics of the hydraulic devices have been built. Based on the calculation results, an assembly drawing of the “throttle-nozzle” type hydraulic amlifier was performed. During the dynamic calculation of the electro-hydraulic servo system, transfer functions have been obtained and the logarithmic characteristics of the open loop of the original system have been constructed. A structural-dynamic scheme of the automatic control system is developed. The electro-hydraulic control system was corrected in a sequential manner. Based on its results, updated logarithmic characteristics have been built, an analysis of the transient in the automatic control system have been performed.
