Optimal structural design of complicated mechanical products based on data mining

Abstract

Complicated mechanical products normally consist of multi-parameter mechanisms. The couplings between two tmechanisms are either strong or weak. The traditional optimal design methods cannot meet the requirements of optimal structural design of the complicated multi-parameter mechanical products. On the basis of analyzing the optimal design methods and the data mining principles, an improved iterative dichotomizer 3 (ID3) algorithm is hereby put forth to bring out an optimal design information model integrated with the data mining technology as well as an optimal structural design system of complicated mechanical products based on the data mining principles. The system is demonstrated by the optimal structural design of the mainframe of the full face rock tunnel boring machine (TBM). An example shows that the data mining technology has fully tackled the issues of the optimal structural design of complicated mechanical products.
