MBD Attributes Template Method of Aeronautical Products

Abstract

Model-based Definition (MBD) expresses the technical information of traditional engineering drawings in a three-dimensional environment. The formed MBD dataset completely express the product information, what changed the product development model and improved product development efficiency. However, the integrity of the MBD dataset is difficult to guarantee and the efficiency to build it is low. In order to solve this problem, this paper proposes to use MBD attributes template method to solve the generation problem of attributes information in MBD dataset. Firstly, the concept and connotation of MBD attributes and MBD attributes template are described. Secondly, the type of aeronautical products and MBD attributes are combed to form MBD attributes template for different types of products. Thirdly, the process of MBD attributes template method is proposed. Finally, the validity of the proposed method is verified by the MBD attributes template construction and attributes values filling of a forging part. The results show that MBD attributes template method not only improves the efficiency of MBD attributes generation, but also improves the integrity and accuracy of MBD dataset.
