摘　　要：提出一种基于条件设计结构矩阵DSM的过程动态组织方法。首先分析了设计过程中考虑条件约束的必要性,通过对设计知识及条件参数的引用建立条件约束模型,然后在传统的参数级DSM模型中引入条件知识维,构成条件DSM三维模型。进而在该模型基础上利用设计过程中时变的条件DSM叠加视图,动态地进行后续过程重构。以汽车等速万向节传动轴设计过程为例,将上述思想用于通用变型设计过程支持系统,结果表明该方法可行,并且有利于提高产品设计的自动化程度。A dynamic process management approach based on conditional design structural matrix was proposed.Considering the possibility of the conditional constraints during the design process,the conditional constraint model was constructed based on the references of the design knowledge and condition parameters,the conditional knowledge dimension was brought into the traditional DSM model,and then the 3D conditional DSM model was obtained.Using the dynamical superimposed conditional DSM view in the model mentioned above,the consequence of the reconstruction in the design process could be reconstructed again and again.The approach presented was finally used in the general variant design system supporting the vehicle CVJ shafts design process modeling,an example was provided and the results demonstrated the higher efficiency and automation degree of the approach presented.
