Abstract
A kind of acquisition hydrostatic thrust bearing oil film three-dimensional pressure field method, the present invention realize the drafting of oil film pressure field perspective view using matlab data visualization function, and the deficiency of oil film pressure maximum value and minimum value position can not be found by compensating for ansys cloud atlas.This method passes through: (1) exporting the analogue data of oil film pressure field and save as Excel file；(2) it opens matlab and imports Excel data；(3) it clicks workspace " yali ", shows array；(4) array code name in workspace is replaced with English alphabet x, y, p, and wherein VarName 3 is remained unchanged；(5) x, y, p of workspace are established into numerical value array respectively；(6) oil film pressure field data visualization procedure is write；(7) new script executes program, generates 3-D graphic；The present invention is suitable for drawing hydrostatic thrust bearing oil film pressure field 3 dimensional drawing field using matlab.
Description
Technical field
The present invention relates to a kind of acquisition hydrostatic thrust bearing oil film three-dimensional pressure field method more particularly to a kind of utilizations
Matlab software carries out the method that post-processing obtains three-dimensional pressure field to hydrostatic thrust bearing oil film pressure field analogue data.
Background technique
The direction that large-sized numerical control process equipment is high to operational efficiency, processing quality is good is developed, and hydrostatic thrust bearing is large-scale
The key component of numerically controlled processing equipment, hydrostatic thrust bearing oil film pressure field are the key factors for influencing hydrostatic thrust bearing performance
One of, it is therefore desirable to hydrostatic thrust bearing oil film three-dimensional pressure field is analyzed using simulation software, passes through oil film pressure field
To judge the superiority-inferiority of hydrostatic thrust bearing.It is to utilize ANSYS software pair to the analysis method of oil film pressure field, in universal significance
Hydrostatic thrust bearing oil film carries out modeling analysis and draws cloud atlas, and the region of highest and lowest pressure can only be searched from cloud atlas,
The position that the highest and lowest point of pressure can not accurately be found out has limitation to the further design optimization of hydrostatic thrust bearing.
It is, therefore, desirable to provide a kind of obtain hydrostatic thrust bearing oil film three-dimensional pressure field method using matlab.Matlab is for calculating
The mathematical software that method exploitation, data visualization, data analysis and numerical value calculate, it has the function of powerful data visualization,
It is usually used in scientific algorithm and engineering drawing.But matlab does not have hydrostatic thrust bearing pressure field data processing module, only provides
User-friendly matlab collection of functions and file tool collection.Therefore, it need to voluntarily be write suitable based on matlab software
The relative program for closing the processing of oil film pressure field data gives full play to the data visualization advantage of matlab, completes static pressure thrust axis
Hold the drafting of oil film pressure field three-dimensional figure.
Summary of the invention
The side that three-dimensional figure is established is completed using matlab processing oil film pressure field data the object of the present invention is to provide a kind of
Method, and by its modularization can not accurately show each position pressure of oil film in treated to solve the problems, such as ansys cloud atlas.
It can be achieved through the following technical solutions using the method for matlab processing hydrostatic thrust bearing oil film pressure field data:
(1) hydrostatic thrust bearing oil film pressure field is exported simulation the data obtained simultaneously after CFD-post calculates completion
Save as Excel file；
(2) it opens matlab software and will be imported in Excel data derived from CFD-post, and pending datas is waited to parse；
(3) after data are parsed, right side workspace " yali " is clicked, shows array；
(4) workspace array code name demand carries out English alphabet x, y, p replacement, and wherein VarName 3 is remained unchanged；
(5) x, y, p of workspace are established into numerical value array respectively；
(6) oil film pressure field data visualization procedure is write according to the code name of workspace numerical value array；
(7) new script executes the program write, generates three-dimensional figure；
(8) it saves picture and closes malab.
Invention effect
The present invention data visualization function powerful using matlab software, it is visual by writing and executing oil film pressure field data
Change program, be successfully established hydrostatic thrust bearing oil film pressure field three-dimensional figure, can be clear sees the pressure of each position of oil film
Force value size is conducive to the position for finding out Pressure maximum value and minimum value, further analyzes, optimizes convenient for hydrostatic thrust bearing
And design, compensate for the deficiency of ansys cloud atlas.Program is subjected to modularized processing, makes hydrostatic thrust bearing oil film pressure field three
Tie up the foundation of figure more rapidly, efficiently.This method process is simple, and convenient for operation, data processing is reliable, is to establish static pressure thrust axis
Hold the optimal selection of oil film pressure field three-dimensional figure.

Specific embodiment
It can be achieved through the following technical solutions:
Step A: after CFD-post data are parsed, clicking File/Export/Export and enter the output page,
Mono- field name word of File is changed to " yali.csv " under options, and selects ROTATE under locations option,
Pressure is selected under Export Geometry Information, save is finally clicked and saves file；
Step B: opening matlab software, importing data clicked under homepage, will save " yali.csv " file on the table
It opens and pending datas is waited to complete load；
Step C: after the completion of data load, the interface single machine upper left corner " delimited files " are being imported, the upper right corner is then being clicked and " imports institute
Select content " under " import data ", close window when showing that data have parsed；
Step D: clicking on the right side of matlab software " yali " under " workspace ", opens tables of data；
Step E: after tables of data is opened, first row data name " Name " is changed to " x ", secondary series data name " VarName2 "
It is changed to " y ", third column data title " VarName3 " remains unchanged, and " the 4th column data title VarName4 " is changed to " P "；
