论文摘要
由于设计效率提高，变分设计是一种公认的CAD技术。它通常显示为CAD模型的参数家族。尽管有效，但是这种工作方式无法处理超越参数变化的设计要求。由于产品自定义的普及，今天的设计要求并不少见。特别是，通常需要从现有的模型结构系列中设计出新的模型，该模型具有结构模式，但具有单独的细节特征。为了促进此类设计要求，本文提出了一种新方法。这个想法是根据由家庭的最大常见设计特征组成的子模型来表达基本的结构模式，然后通过将单个主模型附加到子模型中来构建单个主模型。该主模型是家庭的代表性模型，并包含所有功能。通过删除不需要的细节功能并添加新功能，可以轻松地将主模型适应新的设计，同时结构与家人保持一致。通过一系列案例研究和比较复杂性的比较，该方法的有效性得到了验证。
Variational design is a well-recognized CAD technique due to the increased design efficiency. It often presents as a parametric family of CAD models. Although effective, this way of working cannot handle design requirements that go beyond parametric changes. Such design requirements are not uncommon today due to the increasing popularity of product customization. In particular, there is often a need for designing a new model out of an existing structural family of models, which share a structural pattern but have individually varied detail features. To facilitate such design requirements, a new method is presented in this paper. The idea is to express the underlying structural pattern in terms of a submodel composed of the maximum common design features of the family, and then to build a single master model by attaching to the submodel all detail design features in the family. This master model is a representative model for the family and contains all the features. By removing unwanted detail features and adding new features, the master model can be easily adapted into a new design, while keeping aligned with the family, structurally. Effectiveness of this method has been validated by a series of case studies and comparisons of increasing complexity.
