超高壓軸向柱塞泵關鍵零件的結(jié)構(gòu)分析
[Abstract]:Ultra-high pressure pump is one of the important development directions of hydraulic pump. Based on the structure of the existing high pressure axial piston pump, this paper analyzes the load and structure of the key parts, such as the drive shaft, plunger, slipper, cylinder block and inclined disk, and establishes the corresponding analysis method and flow chart. To solve the main technical difficulties in the process of analysis, to establish the foundation for the development and design of ultra-high pressure axial piston pump. Load analysis includes load analysis of general structure and load analysis of concrete structure. The former is the theoretical basis of this subject and provides the theoretical basis for structural analysis. According to the stress condition of each key part, draw the force diagram separately, mark the position of the force or moment. The equations are established by the knowledge of mechanics, mathematics and hydraulics, and the analytical expressions of the force or torque are obtained by solving the equations. The latter provides the data basis for the structure analysis and is the concrete application of the former. According to the expressions of the forces and torques and the parameters of the concrete structure, the function images and the maximum and minimum values of the forces and torques under 50MPa pressure are calculated by using MATLAB software. Based on the results of the load analysis, the structural analysis of each key part is carried out by using ANSYS Workbench software, and the stress and deformation of the parts are obtained directly, and the results are analyzed. It is pointed out that the maximum stress and total deformation of each part and their positions are the important basis for designing the corresponding parts of axial piston pump with 50MPa working pressure. The results of structural analysis show that the stress and deformation of the existing key structural parts do not meet the requirements of strength and stiffness under ultra-high pressure conditions, and need to be further improved in material, structural design and manufacturing process. The load and structure analysis method established in this paper is suitable for the key parts of piston pump with similar structure. In the design of the superhigh pressure pump, the new structural parameters can be used to analyze the structure and verify the feasibility of the design scheme.
