摘要: 针对机械产品装配结构和装配关系描述问题,提出了面向机械产品装配过程的"装配树"概念.以设计装配图、产品结构树为基础,结合装配过程、装配层次结构和装配顺序特征构建了"装配树"模型,并解决了产品结构树的功能延伸和描述完备性问题.在产品"功能-结构"映射关系明确的前提下,提出了以产品功能为中间转换载体的装配树层次结构建模思路,给出了"装配树"构建方法和步骤.最后以某型柱塞式喷油泵泵油系部件装配树构建为例,验证了"装配树"概念的可行性和构建方法的可操作性.

Abstract: The model of assembly tree was put forward to describe the assembly structure of mechanical products and their assembly relations.The assembly tree model can deal with the functional extension and strengthen the description of the product structure tree which was defined by the designer through assembly drawings.Product structure tree combined with the operations in assembly process,logic relations and other characteristics.The mathematical definition and modeling of assembly tree were proposed on the basis of its formalized description.The idea to take product function as the transforming carrier for the modeling of assembly tree,as well as the construction methodology and steps for assembly tree were also brought forward under the precondition that the mapping relationship between the product function and its structure was definite.The case in assembly process of a plunger injection pump was studied, and proved the assembly tree model feasible.
