Abstract


The relief valve is important pressure of a hydraulic drive system must be used to control components , and its main function : regulation and stability in the maximum pressure of the hydraulic system , the overflow of excess oil ; prevent overload , to ensure the safety of pressure . In order to improve steady-state accuracy and dynamic stability of the relief valve , the researchers on the one hand, from the structure of the relief valve to improve innovation on the other side from the hydraulic control principle . This thesis, a new 2D digital relief valve , two degrees of freedom to the rotary and linear movement of the spool the pilot valve level and the main valve function , greatly simplified the structure of the relief valve , pressure sensor in direct detection system set pressure, the pressure closed-loop control to improve the performance of the 2D digital relief valve , remote monitoring of the pressure and the automatic adjustment . In this paper mathematical modeling of electrical feedback 2D digital relief valve , and its numerical simulation analysis based on the mathematical model , 2D digital relief valve , signal acquisition and control board design , and the last experimental platform on The electrical feedback 2D digital relief valve experimental study . Chapter of this thesis are summarized as follows: Chapter 1 describes the development of hydraulic and electro-hydraulic digital control technology , detailed research status and development trends of the relief valve , and finally expounded the thesis topic background , meaning and completion of the work . Chapter 2 , mathematical modeling of electrical feedback 2D digital relief valve , using numerical solution of its simulation , analysis and relevant parameters on the the relief valve Transient response characteristics of . Chapter 3 introduced the electric feedback the 2D digital relief valve experimental platform composition and design, including the the 2D digital relief valves , digital valve controller , signal acquisition and control board hardware design and software design . Chapter 4 , experimental study of electrical feedback 2D digital relief valve , including the open-loop and closed-loop experiments , and its performance analysis . Chapter 5 Summary and Outlook dissertation contents .
