中文摘要:为了更好地实现面向设计领域的三维CAD模型设计信息的有效重用,提出了一种融合语义的三维CAD模型局部结构检索方法。首先以设计特征作为设计语义信息的基础载体,对三维CAD模型进行结构化表征,并用特征属性邻接图来表示;然后设计能够捕捉不同层次信息的特征描述子,构建融合语义的特征相似性评价模型;最后采用子图同构算法计算查询局部结构与模型库中零件的特征属性邻接图的特征匹配对,以此计算相匹配局部结构的相似度。实验结果表明,该方法能够较好地实现融合语义的三维CAD模型局部结构检索,可以有效地支持面向农机设计领域的三维CAD模型设计信息的重用。基于检索的设计重用方法可为农机装备数字化设计中各类成果的有效重用提供多粒度、精确化和智能化的方法。

Abstract:With the development of digital design and manufacturing integrated technology, 3D CAD model has become the core media of expressing product design and manufacturing information, efficiently locating the desired model from massive candidates, fully exploiting and reusing the implicit knowledge had an important role in improving the mechanical design efficiency and quality in the agricultural equipment field. To effectively realize the reuse of design information of 3D CAD models in design domain, an effective subpart retrieval method of 3D CAD models merging with design semantics was proposed. Firstly, design feature was taken as the basic carrier of design semantic information, the 3D CAD model was structuralized and represented by using a feature attribute adjacency graph(FAAG). Then, a multilevel feature descriptor capturing different levels of information for detailed part design was designed to establish the design feature similarity assessment model. Finally, the matched feature pairs were extracted by using the sub-graph isomorphism algorithm between the FAAGs of the query subpart and the part in the model library to calculate the similarity between matched subparts. Experimental results showed that the proposed method can effectively support subpart retrieval of 3D CAD models merging with design semantics for design reuse. The proposed research results can provide a novel reuse method of multi-granularity, precise and intelligent for the agricultural machinery digital design, and had an important role in improving the mechanical design efficiency and quality in the agricultural equipment field.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
