Design on measurement and control system of automatic test bed of hydraulic cylinder
Abstract Hydraulic cylinder is one of the most important parts of the system, has been widely used in automotive industry, intelligent machinery and other industries, so the hydraulic cylinder of the test has a very important significance。
First of all, we introduce the background and development status of the hydraulic cylinder test-bed, analyzed the problems and development trend of domestic and foreign research, and analysis and put forward their suggestions for improvement, secondly, the working mechanism of hydraulic cylinder test-bed, hydraulic system composition and principle, the test bench process are described。 And on this basis, the design of the control test bench test process electrical schematic。 Thirdly, the paper introduces the key electrical components used in the electrical principle diagram of the hydraulic cylinder comprehensive test bed, and the selection of the components in detail。 Then, this paper introduces the function of the software interface design process, the composition of the interface, the main function of the software, and also briefly describes the operation of the software method。 And the design flow chart is given。 Finally, the installation and debugging of the test bench are given, and the detailed debugging process is described。
