摘　　要：为了能够充分利用企业现有的CAD模型,提出了一种基于语义推理的变型设计方法。首先,对三维CAD信息模型和装配语义信息模型进行了研究,给出了两种模型的构建方法。在此基础上,对语义推理方法进行研究,结合相似性算法实现了CAD信息模型至装配语义信息模型的自动映射。并进一步实现了尺寸约束方程式在一定程度上的自动生成及尺寸约束传递解算。最后,以SolidWorks为三维CAD模型平台,以VC++6.0为编程语言开发出语义映射系统,并以某企业的龙门铣床的主轴箱作为例子,对该系统进行了验证。In order to make full use of existing CAD information model in Enterprise,a variant design method based on semantic reasoning is proposed. First of all, Three-dimensional information model and assembly semantics information model are studied,and two methods of modeling is presented. Based on this ,study on semantic reasoning method,combined with similarity algorithm to puts forward the information from the CAD model automatically map to assembly semantic information model. And to further automatically generated the size constraint equations to a certain extent,and solve the size constraint. Finally,base on 3D software SolidWorks and programming software Visual C ＋＋,system of semantic mapping is developed. All the above mentioned methods and processes are verified by taking a spindle box of plane miller as an example.
