Abstract

The present invention relates to a product structure parameterized design optimization method and system. The method comprises: S1. defining a parameter that needs to be optimized and an optimization goal of product structure design; S2. establishing a three-dimensional parameterized model of a product structure, wherein the model comprises the parameter that needs to be optimized; S3. according to the parameter that needs to be optimized, establishing an optimization combining space of the product structure; S4. generating all three-dimensional design models in the optimization combining space by using the three-dimensional parameterized model; S5. writing a batch processing command set of computational fluid dynamic analysis, and establishing computational fluid dynamic analysis models corresponding to all the three-dimensional design models in a batch processing manner; S6. performing analysis calculation on the computational fluid dynamic analysis models one by one by using a high-performance computer, and outputting all optimization goal calculation results; and S7. comparing all the optimization goal calculation results, and screening out the best three-dimensional design model. According to the product structure parameterized design optimization method and system provided by the present invention, the optimization of product design parameters can be rapidly completed.

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 ...
