摘要

摘要:
针对产品全三维数字化研制中产生的MBD历史建模数据重用性需求，提出了一种基于本体技术的MBD模型知识表达与管理方法，综合考虑几何信息与非几何信息进行检索应用。首先，根据MBD数据集规范性要求，以模型检索为目的，构建本体结构，分为几何信息层与非几何信息层进行具体阐述；其次，根据已构建本体结构，给出几何信息层与非几何信息层相似性对比方法；最终，综合几何信息与非几何信息，实现MBD模型检索。本文方法通过本体技术，将MBD模型数据进行结构化、语义化表达和存储，在此基础上，综合考虑几何信息相似度及非几何信息相似度，进行相似模型检索，实现MBD模型信息重用。

Abstract:
An MBD model knowledge representation and management method based on ontology technique is proposed to meet the reuse requirement of MBD history model data designed in the product full three-dimensional digitalization development, and retrival test is done considering geometric and non-geometric information. First, we construct ontology structure based on the normative requirement of MBD dataset and the purpose of model retrieval, and divide it into geometry feature layer and engineering note layer in detail. Second, the similarity comparison method of two layers is given based on the ontology structure. Finally, MBD model retrieval is completed based on geometric and non-geometric information.The proposed method uses the ontology theory as its basis, achieving structural and semantic expression and storage of MBD dataset, and thus it is capable of achieving the reuse of MBD model information by similar model retrival based on both geometric and non-geometric information.
