Abstract: In order to realize rapid response to performance-driven product design, heterogeneous system of structural variation and simulation analysis was integrated by establishing the coupling correlations between structural variation and simulation analysis with multiple variables. Structural variation was a topological overlap between transplant structures and basic structures. The multiple variables in the process of structural variation were reserved through the multi-level conversion of structural features. By the principal component analysis, coupling design variables were extracted. The coupling model with multiple variables was set up and solved to achieve the multi-variable transmission and feedback of heterogeneous systems. An advanced design platform of integration of structural variation and simulation analysis was developed. It was applied in the design of precision plastic injection molding equipment.
