Abstract：

According to the friction theory and the finite element theory, the friction characteristics under different friction coefficients during stamping were analyzed by connecting the calculated friction force of numerical simulation method with the actual friction force in production. The changing regulation of the friction force during stamping and the influences of different friction coefficients on friction characteristics and the forming quality were studied. The result shows that friction coefficient is growing rapidly with the increase of friction coefficient in the later period of stamping. Furthermore, the evaluation index of sheet forming quality increases, and the thickness of the aluminum alloy sheet is even more. The change regulations of friction forces in the area of thinning and wrinkle are different totally according to the analysis on the friction force varying curve with time under different nodes.
