| 摘 要： | 目前零件的相似程度判断问题,往往是根据已有的经验,精确性难以得到保证。针对这个问题,利用图论中的相关知识,结合图形交换文件(DXF)中的零部件数据信息,给出了一种用于存储零件二维图的数据结构,并且提出了一种针对零件二维图的存储方案,在此基础上讨论了轴类零件图的存储算法,以及基于这种存储方案的轴类零件相似程度的比较算法,为零件相似程度的比较提供了一条比较新的途径。

| Abstract: | At present the compare methods of similar coefficient to the parts,usually accord to the existing experience,the precision is hard to be assured.For this problem the paper proposes a kind of data structure in which the two dimension diagram of parts can be saved according to making use of the related knowledge of graph theory and the data information of DXF,and meanwhile proposes a saving method for this data structure.Then this paper discusses the algorithm of saving shaft parts diagram bases on the data structure,and the compare algorithm of similar coefficient to shaft parts according to the saving method.A newer method is provided for the compare method of similar coefficient to parts. |
