Гидропривод суппорта станка с программным управлением

Abstract

В рамках данной выпускной квалификационной работы была спроектирована система автоматического управления, силовой частью которой является объёмный гидравлический привод с дроссельным управлением и постоянным давлением источника. В качестве методов исследования были применены теоретический анализ и знаковое моделирование рассматриваемого объекта. В ходе статического расчёта выбрано гидравлическое оборудование, рассчитаны элементы аппаратуры и построены статические характеристики основных устройств объёмного гидравлического привода. В процессе динамического расчёта системы автоматического управления составлена структурно–динамическая схема системы, получены передаточные функции отдельных элементов системы и разомкнутого контура системы и по-строены амплитудная и фазовая логарифмические частотные характеристики разомкнутого контура системы. Проведена коррекция системы, по результатам которой получены передаточные функции и построены амплитудная и фазовая логарифмические частотные характеристики желаемой системы и корректирующего устройства.

As part of this final qualification work, an automatic control system was designed, the power part of which is a volumetric hydraulic drive with throttle control and constant source pressure. Theoretical analysis and scientific modeling of the object under consideration were used as research methods. During the static calculation, hydraulic equipment was selected, hardware elements were read and static characteristics of the main devices of the volumetric hydraulic drive were constructed. In the process of dynamic calculation of the automatic control system, a structural and dynamic scheme of the system was compiled, the transfer functions of individual elements of the system and the open loop of the system were written, and the logarithmic and phase amplitude frequency characteristics of the open loop of the system were constructed. The correction of the system was carried out, according to the results of which transfer functions were written and logarithmic and phase amplitude frequency characteristics of the desired system and correction device were construct-ed.
