Embodiment approach 2

[0032] Implementation plan 2: Install all hydraulic cylinders, and all hydraulic cylinders are activated. The vertical hydraulic cylinder 1 and the vertical hydraulic cylinder 2 are arranged in parallel and need synchronous control; the horizontal hydraulic cylinder 3 and the horizontal hydraulic cylinder 4 are arranged in parallel and need synchronous control. Study the position tracking control and output driving force of hydraulic cylinders arranged in parallel under different control strategies.

[0033] By using the experimental platform for dynamic control of the hydraulic servo system of the present invention, the dynamic control experiment that needs to be carried out on the actual forging machine can be moved to the laboratory, thereby greatly reducing the experiment cost and experiment risk.

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 an experiment table, in particular to an experiment table 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 increasing quality requirements for large castings and forgings, the requirements for the process capability of forging manipulators have gradually increased, and new requirements have been proposed for the load capacity, control accuracy, and operating frequency of the forging manipulator. Claim. Due to the long service life of this type of heavy equipment and the slower upgrading of its mechanical system, the common way to improve its performance is to transform it on the basis of the original mechanical equipment, replace with high-performance hydraulic valves, and use PLC and computers. And so on to control, thereby improving its level of automation. This improves the control accuracy and work ...
