基于关系矩阵的装配骨架模型构建研究

为了实现自顶向下的设计方法,分析了以往研究的不足,从便于计算机表达的角度,引入装配语义组成关系矩阵和装配形状特征之间的装配关系矩阵,记录装配体的各装配形状特征组成和各装配形状特征相互之间的装配关系,以便在设计过程中将设计意图和装配约束自动向下游传递(从骨架模型向零件属模型传递)。

On Construction of Assembly Framework Model Using Relational Matrix

In order to better support top-down design,the disadvantages of traditional approaches are first analyzed.Considering the convenience of computer expression,a relational matrix of assembly semantics constitute and a relational matrix of assembly form features are proposed to remember all kinds of form features and their assembly relations.During the design process,the design intentions and assembly restrictions can be translated automatically from assembly framework model to component attribute model.Finally,an example of oil pump design is given to illustrate the availability of this approach.
