Description

technical field [0001] The present invention relates to computer-aided engineering (Computer Aided Engineering, CAE) analysis, more specifically, relates to an optimization method and system for parametric design of product structure. Background technique [0002] CAE analysis is an important link in the design process of mechanical products. CAE analysis can be used for dynamic and static analysis, process simulation and optimal design of products. Through the analysis, the defects in the product design can be found early, the blindness of the design can be reduced, and the product structure design can be changed from the empirical design to the optimal design, thereby improving the competitiveness of the product. Thus, CAE analysis has been widely used to help engineers perform tasks such as analysis, simulation, design, manufacturing, etc. [0003] Taking the axial flow fan as an example, the axial flow fan has a very wide range of applications. It is widely used in the ...
