Abstract


Electro-hydraulic proportional technology has been widely used in various sectors of national economy. As the electromechanical switching actuator in the electro-hydraulic proportional system, the characteristics of the proportional solenoid have a significant impact on the performance of the proportional components and systems. The performances of the solenoid are affected by many uncertain factors, which makes the test methods more important and effective in the researches on the performance of the solenoid.Based on the previous researches on the performance of the proportional solenoid a proportional solenoid test system with the combination of the sensor and control technology is established in this paper. It’s rapid, convenient and capable of the rapid switch between the static test and dynamic test of the solenoid. Not only the performances of the proportional solenoid have been tested, the solenoid has been modeled and its static and dynamic character has been simulated in this topic. The main contents are as follows:In chapterⅠ, the development of electro-hydraulic proportional technology, the structure and principle of proportional solenoids and researches on the performance of the proportional solenoid have been proposed. The significance of the research and primary contents and difficulties are also discussed.In chapterⅡ, the main curve and parameters of the solenoid are analyzed and the overall design of the mechanical structure and control principles are put forward.In chapterⅢ, the realization of various parts of mechanical construction is proposed and the results of the finite element simulation of the whole system prove the rationality of design.In chapterⅣ, the realization of various parts of the principles of measurement is discussed.The main contents are the design of the synchronization between high-speed interrupt acquisition and static control and the achievement of calling Dynamic link library (DLL) in LabVIEW software. In chapter V, the experimental results the test platform are discussed and the dynamic characteristics are analyzed via the MATLAB software.In chapter VI, the researches in the whole paper are summarized and the future researches are put forward.
