基于本体的拖拉机变速器系统设计知识表示研究

Research on ontology-based design knowledge representation of tractor transmission

基于复杂产品的设计知识具有模糊性、多样性、隐含性的特点,按照本体的原理把几种单一的知识表示方法组合起来,采用混合式知识表示方法对拖拉机变速器的设计知识进行表示,提高了变速器的设计效率,实现了领域知识的共享与重用。最后,以轴用弹性挡圈为例,验证了该方法的有效性。

Knowledge representation is the foundation of knowledge discovery,excavation and management. The design knowledge of complex product has the characteristics of fuzziness,diversity,implication and so on. Based on such characteristics,in accordance with the principle of ontology,it combines several single knowledge representation methods to express the design knowledge of tractor transmission. This representation improves the design efficiency of transmission,realizes the sharing and reuse of domain knowledge. Taking the circlip for shaft as example,it verifies the effectiveness of the method.
