摘　　要：为了提高推土机关键零部件装配工艺的智能化水平,研发了一种推土机操纵总成装配工艺云平台,能够对推土机操纵总成装配工艺的知识进行有效管理,当有新的装配需求时提供相应的装配工艺解决方案。首先,根据推土机操纵总成的装配工艺原始数据,构建推土机操纵总成装配工艺的知识本体,并建立操纵总成装配工艺实例知识库。然后将最近邻相似度算法、余弦函数相似度算法与文本型相似度算法进行组合得到一种混合CBR检索算法,通过混合算法检索实例知识库匹配出所需要的装配工艺案例,将该案例作为标准指导装配。如果没有符合要求的案例,则由工艺方案设计者进行修正,并将该案例纳入实例知识库。以此实现对推土机操纵总成装配工艺的智能化管理、使用与改进。In order to improve the intelligent level of the key components assembly process of bulldozers,this paper developed a cloud platform for the assembly,which can effectively manage the knowledge of the assembly process of bulldozer control assembly,and provide corresponding assembly process solutions when there is a new assembly demand.First,according to the original data of the assembly process of the bulldozer control assembly,construct the knowledge body of the bulldozer control assembly process,and establish a knowledge base of the assembly process example.Then the nearest neighbor similarity algorithm,cosine function similarity algorithm and text-based similarity algorithm are combined to obtain a hybrid CBR retrieval algorithm.The hybrid algorithm is used to retrieve the example knowledge base to match the required assembly process cases,and the case is used as a standard guide assembly.If there is no case that meets the requirements,the process plan designer will correct it and include the case in the case knowledge base.In this way,intelligent management,use and improvement of the assembly process of the bulldozer control assembly are realized.
