| Fuel Static Experiment Comprehensive Platform is a new test equipment speciallydesigned for testing performance of the combination valve and the independent valve.Aim at the basic technical requirements, The schematic diagram of hydraulic controlsystemã€hardware composition block diagram of electrical control system and work flowchart of software system for this comprehensive platform was given. And focus on key,difficulty encountered in the development were introduced in detail, and verify thecorrectness of the design scheme.This paper generally did the academic research and work listed bellow:(1) Introduces the development of this test equipment at home and abroad,analyses thedevelopment necessity and market prospects of the test equipment.(2) Introduces the importance and value of the independent valve and the combinationvalve in aircraft engines, detail description was given for the structure and workingprinciple of the hydraulic system, control system.(3) Determine the mathematical models of all parts of the temperature control system ofthe tester. Established computer simulation model of the temperature control system.Simulation of the temperature control system using Simulink simulation software. Toverify the control temperature system deficiencies and improvement scheme, controltemperature system determined the final.(4) The comprehensive tester temperature control system was conducted in-depth anddetailed analysis. Combining the temperature control method and temperature controlsystem mathematical model and put forward a set of temperature control system. Thetemperature control process using the Simulink toolbox for simulation. Through thesimulation, the temperature control system can realize the control precision is±2℃.Fullymeet the reliability of the tester and has higher requirements for temperature control.Studies have shown that: the combination valve and the independent valve is an important part of the aircraft engines. Due to its structure and characteristics of complexity,Need to adopt the method of computer simulation experimental research on it. Simulationresults show that this temperature control system is a simple and effective temperaturecontrol scheme, can get more and more effective in controlling field. The same temperaturecontrol has a certain practical significance and reference value research. |
