[Abstract]:The flow characteristic of the pneumatic element is a very important technical index. It is of great significance to understand the flow characteristics of the pneumatic components accurately. The pneumatic components are composed of one or more basic components. Through the study and analysis of the flow characteristics of these basic components, the mechanism of their work is deeply understood. In order to comprehensively and accurately grasp the change rule of the flow characteristic parameters of pneumatic components, it has important practical significance for the development and research of pneumatic technology.
The throttle hole is a common basic component in the pneumatic components, and the current research is less. Therefore, this paper, based on a certain international cooperation project, takes the fixed throttle as the research object, based on the theory of flow characteristics, combined with the test method of international standard ISO6358, the combination of theoretical research and testing, and the contrast method of software simulation, and the design needle. The relationship between the structure parameters of the fixed throttle hole and the parameters of the flow characteristic is analyzed by the experimental method of the flow characteristics of the fixed throttle. The main research work in this paper is as follows:
(1) to analyze the current research status of the flow characteristics of pneumatic components and throttle holes at home and abroad, to determine the research direction and research ideas in this paper, and to provide a reference for the research of simulation analysis and experimental methods.
(2) theoretical analysis and Research on the flow characteristics of fixed throttle holes. First, the basic theory of the flow characteristics of fixed throttle holes is analyzed, and several common testing standards and presentation methods of flow characteristics are introduced. Then, according to the structure characteristics of the fixed throttle hole, the suitable flow specificity and testing standards are selected to set up the test system. Finally, the formula for calculating the flow characteristic parameters is derived, and the relationship between the structural parameters of the fixed throttle orifice and the flow characteristic parameters is derived.
(3) the flow characteristics of the fixed throttle hole are simulated and analyzed. ICEM CFD is used to mesh the established model, and the good model is introduced into the Fluent for simulation. The correctness of the modeling and simulation is verified through the comparison of the theoretical analysis and the simulation results. Then the structure parameters and the flow characteristic parameters of the fixed throttle hole are then fixed. A more comprehensive and in-depth analysis of the relationship.
(4) the experiment of fixed throttle hole is studied. According to the selected test standard, the test system is designed, and the operation process of the experiment is perfected according to the experimental results. Finally, the experimental results, simulation and theoretical analysis are compared to verify the feasibility of the experimental method, analyze the cause of the data error and the structure of the fixed throttle hole structure. The relationship between number and flow characteristic parameters is fitted by data, and the relationship between them is obtained.
The research work of this paper shows the simulation analysis and experimental method of the flow characteristic of fixed throttle hole. The research method of this paper has theoretical guiding significance and engineering application value for the study of the flow characteristic of fixed throttle.
