针对复杂机电产品中线缆工程语义信息统一表达难、线缆复杂拓扑结构难以表示和存储的问题，提出基于本体和无向图的复杂线缆信息表达与存储分析方法。首先建立了基于布线设计、装配工艺规划和仿真分析3个维度的线缆信息集成模型；然后利用本体技术对模型信息进行了本体建模，增强了线缆语义信息的表达；最后利用一种水平分割算法将线缆零件划分成一个无向图，在此基础上建立邻接表，实现了线缆零件无向图在计算机中的存储和表达。通过将该方法应用到某线缆零件的实际分析中，验证了文中方法的可行性。%It was difficult to afford unified expression and storage for semantic information and complex topological structure of the cable harness in complex mechatronic products. Aiming at this problem, a method of expression and stored analysis on complex cable harness information based on ontology and undirected graph was proposed. A cable harness information integrated model based on three-dimensional degrees of wiring design, assembly process planning and simulation analysis was established firstly. Then the expression of cable harness semantic information was enhanced through the ontology modeling of the model information by using the ontology technology. Finally, divide the cable harness part into an undirected graph by using a horizontal split algorithm. On this basis, an adjacency list of undirected graph was built, and the storage and expression of the cable harness undirected graph in the computer were realized. A certain cable harness part was taken as the application case to verify the feasibility of this method.
