Principal Component Analysis of Structure Model Indexes on Composite Friction Materials

Abstract:

For the copper-based composite friction material, the statistical models of the element structure were given in this paper to pick up the main components, that was, through the principal component analysis on basic element model of surface structure, the two kinks of main indicators or indexes are ascertained can be found from the original four indicators. Here, the main components were the area radio and long radius, the others among the four were short radius, inclination. Moreover, the indicator reduction criterion was put forward as a general rule by this paper.
