Abstract

The invention relates to a CAE (Computer Aided Engineering) analysis based product structure optimization method and system. The CAE analysis based product structure optimization method comprises step 1, establishing a finite element mesh model of a product structure before optimization through an application module which is arranged in a computer system and receiving material parameters of the structure; step 2, receiving boundary conditions and loads of the modal analysis under the static analysis and of constraint condition, wherein the boundary conditions and loads are defined based on the working conditions under two working states, loading the finite element mesh model and obtaining a response result through calculation; step 3, establishing a design space and an off-design space according to the response result; step 4, receiving topology optimization parameters which are defined according to the design space, the off-design space, structural loads and the response result, establishing a topology optimization model, completing the optimization analysis and obtaining an optimization result; step 5, reestablishing the finite element mesh model according to the optimization result, performing loading in the way as same as that in the step 2 and obtaining a response result of the product structure after optimization through calculation. According to the CAE analysis based product structure optimization method and system, the performance requirements are met and meanwhile the lightweight design is implemented.

Description

technical field [0001] The present invention relates to computer aided engineering (Computer Aided Engineering, CAE) analysis, more specifically, relates to a product structure optimization method and system based on CAE analysis. 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] Take the control arm of the front suspension of the car as an example. The control arm is an important safety and functional par...
