Application of Freeform Surface to the Parametric Design of Plate Sheet Structure

Abstract

This paper constructs a small-scale, lightweight structure with complex freeform surfaces via parametric design. First, the method of freeform surface modelling and parametric design were introduced, and combined into the parametric design aided freeform surface modelling. Then, the parametric design and software for complex surface structure were determined. On this basis, the small-scale structure was conceptualized and the model was improved in the design phase. The PP sheet was selected as the final simulation material and the model was established according to the specified method. The stress deformation of the structure was simulated to correct the stress defects in the design, while the airflow impact was simulated to verify the rationality of the structural form. The results show that the parametric design helps apply complex freeform surface to small and light structure and assist the generation of the designed form. The research findings shed new light on the application of parametric design in the field of structure.
