摘　　要：为了减少不同配合类型下配合偏差对尺寸链生成的影响,使生成中相关的公差信息能被计算机更好的理解和共享,将本体技术引入到装配尺寸链的自动生成中。首先,通过网络本体语言(OWL)构建装配尺寸链表示模型,根据特征面之间是否有间隙将装配约束类型分成漂移配合和固定配合,将间隙量映射成漂移配合。在此基础上运用OWL断言描述模型中各层的约束关系。然后,构建装配尺寸链本体模型及其推理规则,采用OWL描述其结构化知识,建立相关的类、对象属性和数据属性。其次,对漂移配合类型的装配约束关系进行标记,并进行计量分析,利用SWRL描述推理规则得出偏差影响最小且最短的尺寸链。最后,在建立的本体模型和规则语言的基础上,以滚轮为实例验证了方法的可行性。In order to reduce the influence of the matching deviation on the dimension chain generation under different mating types,the related tolerance information in the generation can be better understood and shared by the computer,and the ontology technology is introduced into the automatic generation of the assembly dimension chain. Firstly,the assembly dimension chain representation model is constructed by the network ontology language(OWL). The assembly constraint type is divided into a drift fit and a fixed fit according to whether there is a gap between the feature faces,and the gap amount is mapped into a drift fit. On this basis,the OWL assertion is used to describe the constraint relationship of each layer in the model. Then,build the assembly dimension chain ontology model and its inference rules,use OWL to describe its structural knowledge,and establish related classes,object attributes and data attributes. Secondly,the assembly constraint relationship of the drift coordination type is marked,and the measurement analysis is carried out. The SWRL is used to describe the inference rule to obtain the smallest and shortest dimension chain with the deviation. Finally,based on the established ontology model and rule language,the feasibility of the method is verified by using the wheel as an example.
