摘　　要：在分析数字化预装配需求的基础上,提出一个基于配合特征的分层次产品装配模型,能高效地支持数字化预装配中的各项任务,满足信息完备性、一致性等要求,便于信息的高效按需抽取。并给出装配模型的建立过程及基于工程知识的装配配合约束类型识别方法、配合特征相对自由度推理算法。最后给出一个具体的应用实例。A hierarchy assembly model based on mating feature is presented after analyzing the digital preassembly requirements,which can support the tasks of product digital preassembly with great efficiency.This model has such characteristics as completeness and consistency,and from the model the requirement the information can be extracted according to need with high efficiency.Then,the method of building the assembly model,recognizing mating constraint type based engineering knowledge,the algorithm of inferring relative freedom of mating feature are given. Finally,an example is given to illustrate the modeling approach.
