Fuzzy association rules mining method for design knowledge of mechanical structure symmetry

Structure symmetry is a common phenomenon in mechanical product structure, which plays important roles in realizing the design demands of mechanical product. This article using the method of multidimensional fuzzy association rules mining to mine design knowledge from the instance database, the mining results can guide the scientific application of structural symmetry in mechanical product structure design. First, the data to be excavated in the case database is processed by fuzzy method, and then association rules mining algorithm is used to mine the fuzzy association rules between structural symmetry and mechanical product function, performance and restriction, then the design knowledge of structural symmetry in mechanical product structure is established. The research result of this article is the theoretical basis of the further research on application rules of mechanical structure symmetry.
