机械产品装配序列规划研究

研究装配序列规划作为装配工艺中的核心内容,对实现生产自动化有着十分重要的意义,是目前国内外工艺领域的研究热点．在比较了各种装配序列规划方法的基础上,以某实际产品为例,借助干涉矩阵,就装配序列的生成展开了讨论．为防止随着装配单元数量的增加,产品的装配顺序方案呈指数增加,从而产生组合爆炸或大量的交互问答,同时也为了获得行之有效的装配序列．在已获取的一系列装配序列的基础上,综合装配约束关系及子装配本的识别对装配序列的获取进行了优化,生成合理的接近实际的装配序列．

Study on Mechanical Product's Assembly Sequence Planning

With the rapid development of FMS( Flexible Manufacture System) ,CAX( Computer Aided Design Software) and information technology, the manufacturing of worldwide will be in the automatization epoch. However, the assembly technology has become the weakness of modern manufacturing due to its development lag behind design' s development. Therefore, the research of assembly sequence planning is not only the core of assembly process, but also plays an important role in realizing the automatic production and becomes the hotspot in technical study field both home and aboard. Having compared with some kinds of assembly sequence planning methodologies, and take a real product as an example, we discuss how to generate the sequence by interfere matrix. In order to prevent getting too much feasible sequences and the exploding of ask and answer between man and machine while components or parts increasing, we use the restriction information as well as the recognition of subassemblies for further optimization based on the sequences we have obtained. In this way, both the time we spend on getting the sequence and the procedure will be less while the efficiency of generating sequence will be higher.
