자전거 편집설계를 위한 CAD 모델 라이브러리 구축 및 활용

A library of parametric CAD models should be provided for the reuse of design data in configuration design. Mechanical products have many options and parameters, which in turn, require a large number of CAD models for configuration designs. Existing methods for library construction are limited in their ability to decrease the number of CAD models and ensureindependency between theconfiguration design system and the library. To solve these problems, we propose a method thatcontrolsa CAD library based on part-shape information model, and also present its technical details. To verify the proposed method, a CAD library for bicycles was constructed and design modification experiments usinga prototype part-shape controller were performed. From the experiments, we found that the proposed method can effectively decrease the required number of CAD models by reusingmodels for configuration designs.
