摘　　要：针对航空制造型企业对机械零件检索的需求,提出一种基于语义的三维航空CAD模型检索算法。首先将模型进行分割,分割为一些有意义的子部分,然后对这些子部分进行语义描述和标注,并建立CAD模型的本体表示,最后基于CAD模型语义本体实现模型的相似性评价。结果表明,本文算法能较好地实现模型语义检索,检索性能高于通用领域的检索算法,可以实现机械模型设计和制造知识的重用。For aviation manufacturing enterprises demand retrieval of mechanical parts, an semantic-based algorithm for three-dimensional CAD model retrieval is presented. The model is segmented into many relevant sub-parts. Then, semantic descriptions and annotations are attacched to these sub-parts. Finally, the similarity of the models is evaluated based on the semantic ontology 3D CAD model. Experimental results show that this method can achieve CAD model retrieval and the retrieval performance is higher than the common retrieval algorithms and can achieve the reuse of design and manufacture.
