Experiment table for kinetic control of hydraulic servo driving system

Abstract

The invention relates to an experiment table for kinetic control of a hydraulic servo driving system. The experiment table comprises a supporting frame, a front big shaft, a rear big shaft, a first suspender, at least one vertical hydraulic cylinder, at least one horizontal hydraulic cylinder, a pitching hydraulic cylinder, a control unit and a detection unit, wherein the front big shaft and the rear big shaft are fixed on the supporting frame respectively; the suspender is connected with the front big shaft and can rotate around the front big shaft; the at least one vertical hydraulic cylinder is used for realizing movement of a girder and a load in the vertical direction; the at least one horizontal hydraulic cylinder is used for realizing movement of the girder and the load in the horizontal direction; the pitching hydraulic cylinder is used for realizing pitching movement of the girder and the load; the control unit is used for controlling the vertical hydraulic cylinder, the horizontal hydraulic cylinder and the pitching hydraulic cylinder to move; and the detection unit is used for detecting pressure values and displacement values of the vertical hydraulic cylinder, the horizontal hydraulic cylinder and the pitching hydraulic cylinder. By using the experiment table for carrying out an experiment on the stability and the reliability of a controller, the experiment can be transferred from an actual mechanical system into a laboratory so as to greatly reduce the experiment cost and the experiment risk.

Description

technical field [0001] The invention relates to a test bench, in particular to a test bench for dynamic control of a hydraulic servo drive system. Background technique [0002] With the large demand for large castings and forgings in my country's major industries and the improvement of quality requirements for large castings and forgings, the requirements for the process capability of forging manipulators have gradually increased, so new regulations have been put forward for the load capacity, control accuracy, and working frequency of forging manipulators. Require. Due to the long service life of this type of heavy equipment, the replacement speed of its mechanical system is slow, so the common way to improve its performance is to transform the original mechanical equipment, replace it with high-performance hydraulic valves, use PLC and computer And so on to control, so as to improve its automation level. This improves the control accuracy and work efficiency of the forgin...
