3D engineering design software CATIA platform, using its powerful 3D modeling capabilities , two, three-dimensional model , by computer intelligent processing , axial fan fast , convenient design . This paper briefly describes the basic theory of axial fan with similar design characteristic curve ( or characteristic parameter) , ventilator aerodynamics slightly Figure key technologies and CAD systems . By the axial fan performance characteristics ( pressure , flow rate , and the number of revolutions , etc. ) , geometric characteristics and constraints analysis of the relationship , based on model experiments or use practice good performance axial fan air dynamics thumbnail and dimensionless characteristic parameter ( or characteristic curve) library , application of the similarity theory fan type determination and selection , quickly and accurately selected to meet user requirements , the good performance of the ventilator ; then in the the CATIA platform using parametric methods , object-oriented technology , size drive functions for three-dimensional design of turbine components ; Finally, the system can be in the VB environment, the use of database technology , the design process of the modular software design techniques developed fan , fan design of man-machine interface , designed for direct output fan of two - dimensional engineering drawings , realized from the conversion of the three-dimensional to two-dimensional . In this paper, to determine the selection module design module , auxiliary function modules to achieve computer parametric design of the fan , the progressive realization of the fan design automation can greatly improve the efficiency of the turbine design , to shorten the product development cycle axial fan , reduce fan development costs , enhance their market competitiveness .
