Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing:

[0011] First, the servo hydraulic cylinder to be tested is connected to the hydraulic control device 2 through points A and B, and then the hydraulic control device 2 is connected to the pump source and the accumulator group 1 to form a complete hydraulic control circuit. The test servo hydraulic cylinder is connected to the hydraulic control device 2 and the computer 5, and then the tested servo hydraulic cylinder is connected to the loading device 3 to form a complete mechanical-hydraulic-electrical closed-loop control system.

[0012] After the test system is set up, start the pump source and the accumulator group 1 to maintain the working pressure, select different input signals through the computer 5 and the closed-loop controller 4, drive the hydraulic control device 2, and test the hydraulic cylinders in order Test as follows:

[0013] (a) Run-in test

Abstract

The invention belongs to the technical field of mechanical engineering, and discloses a test system and a test method used for a servo hydraulic cylinder. In the invention, a hydraulic control device is respectively connected with the servo hydraulic cylinder to be tested, a pump source and an accumulator to build a complete hydraulic control loop; a closed-loop controller is respectively connected with the servo hydraulic cylinder to be tested, the hydraulic control device and a computer; and then the servo hydraulic cylinder to be tested is connected with a loading device to constitute a complete mechanical-hydraulic-electrical closed-loop control system used for the servo hydraulic cylinder testing. The invention has convenient operation and wide application range, and can comprehensively and systematically judge dynamic and static properties of the servo hydraulic cylinder to be tested by taking test indexes such as cleanliness, frictional characteristic, step response time, hysteresis loop, and the like aiming at different servo hydraulic cylinders in an equipment factory and engineering production field.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering and discloses a testing system and testing method for a servo hydraulic cylinder. Background technique [0002] In the field of mechanical engineering technology, the precision of products has higher and higher requirements for control precision, and various hydraulic servo control systems have been used more and more widely. The hydraulic servo control system is a typical closed-loop high-precision adjustment control system, and it is often the core guarantee technology for high-quality products and high output of a production line. The hydraulic servo control system composed of machinery-hydraulic-electricity as the main link is characterized by the close integration of electromechanical hydraulics and high control precision, but at the same time it is difficult to debug and troubleshoot. As the actuator of the hydraulic servo control system, the servo hydraulic cylinder has a gr...
