Description
Technical field
Emulation and production method the present invention relates to a kind of fan blade.
Background technology
Fan blade is a kind of curved surface part, it only have dimensional accuracy requirement, but also functional property requirement.Only
There is the design for reaching requirement, can just carry out die sinking volume production.So to be tested before die sinking and adjustment flabellum dynamic balancing.Have
When even also needed to after die sinking by very long testing mould and modification mold process.So, it is necessary to fan before die sinking
Blade carries out single-piece or a small amount of production is tested.Current production of the fan blade before die sinking is that flabellum is split into portion
Part, through CNC it is machining after, the integral impeller of gluing, dimensional accuracy and internal stress are difficult to control to, and cause dimensional accuracy
Low, the overall mechanical strength of fan blade is relatively low, and uncontrollable Structural Errors are brought to dynamic balancing and wind quantity test.Do not have at present
There is the method that the effective method of energy solves the high efficiency manufacture and inexpensive trial and error of fan page test sample, while also lacking preceding
Finite element design analysis when phase is designed, also increases trial and error number of times.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provide it is a kind of reduce trial and error number of times, compact dimensions high precision can one
Body chemical conversion type, overall mechanical strength is higher, is easy to emulation and the production method of the fan blade of test.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of emulation of fan blade and production method, the method include following three step：
(1) action balance analog simulation test, is entered to the threedimensional model of fan blade using finite element analysis software, then
According to test result, optimize design and change；
(2) Stereolithography equipment, is calibrated so that laser facula initial position and shaped platform center complete
Cause, then the three-dimensional modeling data of the fan blade be placed into shaped platform center, make the fan blade center with
Shaped platform center overlaps, and then laser facula focuses on the surface of photo-curing material, is allowed to by point to line, by line to face
Consecutive solidification, so as to carry out successively printing shaping to the fan blade；
(3) fan blade of printing shaping, is taken out, actual size detection and dynamic balancing is carried out to the fan blade
Test.
Photo-curing material is liquid photosensitive resin, liquid photosensitive resin yield point tensile strength 55mpa, elongation at break
57%, density 1.10g/cm3；Optical maser wavelength uses 455nm.
The beneficial effects of the invention are as follows：Due to entering action balance analog simulation test first with finite element analysis software,
Design effect can be gone out with initial analysis, and make optimization modification, therefore the number of times of trial and error can be reduced.Simultaneously using solid based on light
Change the production technology of forming technique, compact dimensions high precision can integrated molding, it is to avoid the fractionation CNC to fan blade adds
Work, the dimensional accuracy and overall mechanical strength of fan blade are obtained for guarantee, have reached the requirement of design, are easy to test.
Specific embodiment
Herein it should be noted that being used to help understand the present invention for the explanation of these implementation methods, but do not constitute
Limitation of the invention.
A kind of emulation of fan blade of the invention and production method, the method include following three step：
(1) action balance analog simulation test, is entered to the threedimensional model of fan blade using finite element analysis software, then
According to test result, optimize design and change；
(2) Stereolithography equipment, is calibrated so that laser facula initial position and shaped platform center complete
Cause, then the three-dimensional modeling data of the fan blade be placed into shaped platform center, make the fan blade center with
Shaped platform center overlaps, and then laser facula focuses on the surface of photo-curing material, is allowed to by point to line, by line to face
Consecutive solidification, so as to carry out successively printing shaping to the fan blade；
(3) fan blade of printing shaping, is taken out, actual size detection and dynamic balancing is carried out to the fan blade
Test.
Enter action balance analog simulation test first with finite element analysis software, finite element analysis software can be used
ANSYS initial analyses go out design effect, and make optimization modification, therefore can reduce the number of times of trial and error.Stereolithography is set
Standby calibration, the error that laser light scattering phenomenon can be avoided to cause fan blade in forming process causes leaf weight to differ.
The material that Stereolithography equipment is used is LA04 label photosensitive resins, and reaching the fan blade mechanical strength after shaping will
Ask, photosensitive resin yield point tensile strength 55mpa, elongation at break 57%, density 1.10g/cm3, this kind of photosensitive resin institute
The part of shaping has enough mechanical strengths, can reach the requirement of test, and with the laser corresponding to kind of photosensitive resin material
Wavelength is 455nm.3D measurements are carried out using 3D scanning devices after curing molding, and compares correlation values, motor rotation is installed and is surveyed
Examination, air quantity and ANSYS the emulation data for testing out fan blade are compared, therefore use finite element analysis software initial analysis
Be effectively reduced trial and error number of times with the combination of Stereolithography, compact dimensions high precision, integrated molding, overall mechanical strength compared with
High, it is to avoid fractionation CNC processing to fan blade, the dimensional accuracy and overall mechanical strength of fan blade are obtained for guarantor
Card, has reached the requirement of design, is easy to test.
Embodiments of the present invention are the foregoing is only, the present invention is not intended to limit, for those skilled in the art
For, the present invention can have various modifications and variations.All any modifications within principle of the invention, made, equivalent,
Improve etc., should be included within the scope of the present invention.
