Paper Abstract:
|
As the early stage of automobile production, the form design plays an important part for the products success in the future market. However, the form design of a car is difficult and time-consuming because it is related to the considerations not only on aesthetics but also on engineering technology. This study proposes a parameterized CAD model used for the car form design and discusses the method to modify the model by changing some parameters. By analyzing the relationship between the sub-surfaces on the car surface, a geometry model is established for the half-car surface by 16 quadrilateral sub-surfaces. Each sub-surface is described by CE-Bézier surface. In this way, a parameterized CAD model for the half-car surface is established by taking the control points, shape parameters and trimming parameters of CE-Bézier surface as the parameters. Furthermore, the modifying methods for the CAD model are proposed by changing different kind of parameters. |
