Abstract
To analyze the characteristics of ring stiffened cylindrical shell in the design space, the full factorial experiment design method is used to obtain all feasible solutions in given ranges. The cylindrical shell has multiple objectives and variables, so the analysis of the characteristics of cylindrical shell is a multivariate analysis problem. Multivariate analysis approaches correlation analysis and cluster analysis are used to study the structural characteristics of ring-stiffened cylindrical shell. The results of multivariate analysis indicate the incompatibility of attributes and the similarity and complicated relations among attributes and variables of cylindrical shell. The useful conclusions obtained from multivariate analysis approaches can be used as reference in engineering design.
