为进行高重合度人字齿轮系统设计，采用知识发现方法获得多因素对啮合刚度的影响规律。在多次仿真数据的基础上，采用模糊聚类方法对人字齿轮副啮合刚度进行分类。基于粗糙集理论完成给定仿真数据集的离散化、属性约简以及属性值约简，从而获得综合考虑多因素的决策影响规则集，最终建立各结构设计因素与高重合度人字齿轮副啮合刚度之间的知识规则。新样本的综合判断表明，所获得的设计知识对高重合度齿轮系统的设计具有一定理论指导作用和实用性。
為進行高重閤度人字齒輪繫統設計，採用知識髮現方法穫得多因素對齧閤剛度的影響規律。在多次倣真數據的基礎上，採用模糊聚類方法對人字齒輪副齧閤剛度進行分類。基于粗糙集理論完成給定倣真數據集的離散化、屬性約簡以及屬性值約簡，從而穫得綜閤攷慮多因素的決策影響規則集，最終建立各結構設計因素與高重閤度人字齒輪副齧閤剛度之間的知識規則。新樣本的綜閤判斷錶明，所穫得的設計知識對高重閤度齒輪繫統的設計具有一定理論指導作用和實用性。

In order to help to design herringbone gear system with high contact ratio,a knowledg discovery method was proposed,which combined fuzzy mathmatic with rough sets theory (RST).At first,a fuzzy clustering method was applied on the simulation results and helped to acquire the classi-fication of the tooth meshing stiffness.Then,the design decision rules were deduced by discretization of simulation parameters,the reduction of attributes and values which were based on the RST.And these rules show the relationship among the meshing stiffness and design factors.At last,the illus-tration of three new samples demonstrates the validity of this new method in application of knowledge discovery of simulation data.
