[Abstract]:Based on the basic and applied experimental research of W seal ring in aerospace, the testing content and test method of W seal ring performance are studied. Based on the trend of automation of test process, The automatic computer control and modern integrated technology and the test contents of the test bench are designed. The test software is developed and the measuring and controlling system realizes the automatic processing of the measurement and control process and the data collected after the test. The main work of this paper is to analyze the design scheme of the measurement and control system in detail, to design and implement the functional modules of each subsystem, and to complete the overall scheme design of the measurement and control system of the test bed. The electrical system scheme design of the test bed, the detailed engineering design of each subsystem scheme, the hardware and equipment selection of the measurement and control system, the design and analysis of the test software and the structure design of the measurement and control system are completed. Based on the configuration software of "easy to control" project, the man-machine interface of the upper computer test software is developed, which includes the main interface, the interface of each sub-system, and the main functions of the interface are as follows: control area, monitoring area, alarm area, visual display of measurement and control data. The important parameters are saved automatically, the operation is convenient and reliable, the key test parameter data chart is displayed in real time, and the calibration scheme of parallelism between upper and lower pressure plates is designed. It is mainly used to monitor and calibrate the nonparallelism of pressure plate by software. Realize the communication between different equipments, complete the design of the zero plan of displacement and deformation of the test bed, complete the design of the schematic diagram and the engineering diagram of the electric gas cabinet of the test bed, compile the software design specification, The test and control system not only improves the degree of automation, measurement precision, control precision and reliability of the test bed, but also realizes the manual inconvenient or unrealized off-condition test, etc. The test efficiency has been greatly improved, and it has certain application value to the scientific research units of aeronautical and aerospace engines and related fields.
